ominousone I ran the 91 Oct Uncle Chip on my 2014 Sonata 2.0T and then the same unit on my 2013 GC R-Spec. Always seemed fine. My dad runs the 93 octane and he is slightly faster than me, prolly the claimed 20 hp difference from 91 oct to the 93 oct tune. Dad's been running for over a year with no issues. I'd prolly sell my Uncle Chip pretty cheap is anyone would be interested. I don't need it any longer since I went to the 3.8.

The Hyundai rated 274 HP came up with only 200 RWHP on a Dynojet. That's, what, about a 30% loss?? Most vehicles are under 20% loss to the wheels, including our Twin Turbo Stealths with AWD... The decent news is that my dad put on the Lap3 Uncle Chip 93 octane tune, while the car sat on the dyno, and gained over 40 RWHP. Both dyno numbers were within the same hour on the same dyno. The dyno guy was even pretty impressed. So, that's a nice mod for the 2.0T.
I have not run my recently acquired 2015 3.8 Base auto, but from what I have seen, the 3.8 rated by Hyundai at 348 HP, shows around 270 RWHP from dyno sheets I have seen.
Otherwise the GC is a fun, great handling car to drive. And a great looking car.

Are you the only one running the lap 3 uncle chip? I read they weren't the safest for turbo cars. My biggest gripe is the extremely slow shifting (2013 2.0T). I make sure the car has been running a while before I try to do anything quick.

AKGC I'm getting 16.6 mpg 2 weeks after filling up... but it's cold here and I live in the city.... and the many things I've done to it. lol
I'm guessing I have a snapped piston ring, but I have a spare block that's taking me forever to rebuild (life getting in the way).
I should do a compression test, but I keep forgetting to grab it from my dad.


As far as my complaints:
weight
That it has a back seat (I don't use it a seat. I just use it for storage, which means more crap I have to clean out lol)

AMBCoupe Sheeeeeeit.

My Jeep Wrangler gets about 18L/100km, or 13ish mpg.

Lifted 2", and being on 35" tires that weigh around 90lbs each doesn't help much though I guess...
12-17-2018 01:55 PM
Red Raspberry 35.5 mpg is my best mileage on a tank. Not by the dash gauge either. 31.3 is my current running average over 79 fill ups.

I was actually averaging 32 that day, but saw I could get more, so I tried to get it that high. I did not get it past 35.0 though.

I still average 30-32 depending on temps if I just drive normally, but if I'm hooning it, I'll still get 26+. Today I drove 2 hours with the AC on often times doing 100+ and still got 27mpgs.

Your average milage will reset when you add fuel. Mine starts out at 8mpgs and will rise from there. Worst I ever got was 14mpg but that was at the last track day event

mrGainZ I get around that range of 35-38 after a few moments I fill my gas tank up. Then as my meter goes down.. my MPG goes down with it averaging around 22-24 when needing to fill up again.

I can't agree more with this last piece. I got extremely lucky with my SRT, but it did have it's nicks. It was mostly problem free and I enjoyed the hell out of it from driving it 100% stock for a full year before modding it to altering it and causing problems. Most of which I can admit was my fault, like ripping an axle boot while dropping the suspension... Plus, it had a rust problem (my main issue with it). I have 4 friends in close proximity that all have SRTs, currently, and they've gotten pretty lucky with them too, they've just had their share of bad juju with them as well. All in all, you're right. We do look back fondly on our past cars and tend to forget all the struggles with it. Heck, for some people, all they can remember IS the struggles with it.

I dont think it was that ugly, common
07-07-2016 12:41 PM
GenCoupeGeek I will give you this... Dodge did well on the Neon SRT4... in spite of the fact that it was an ugly little car. I will point out that stock the car only produced 230 HP but the weight difference made it feel faster. With that said, the Neon was made before the NHTSA forced car manufacturers to add additional safety features that made all cars heavier. This is the reason why I compared 2013 with 2013s. Since there are no 2013 Dodge Neons in existence, it's hard to make an apples to apples comparison. For that you'd have to pick the 2013 Dodge Dart... which falls into the same class as the GC... weighing in at a mighty 3,348 lbs. From a safety standpoint (by today's safety standards), the Neon was a death trap... receiving marginal and poor ratings from the Insurance Institute for Highway Safety.

So, don't blame the manufacturer for the weight gain, thank your politicians... all cars weigh more than they did in 2005. If you are ever in an accident in the future... you'll be thankful that you did in a "heavy" Genesis Coupe. I have seen a LOT of accidents posted online here, Facebook, and the general media involving Genesis Coupes... and I have only heard of one fatality of either a driver or passenger in a GC actually dying in the crash. You'll find that the extra safety measures added to this and all modern cars (which added significant weight to them) pays off when you actually need it to.

w/r/t the backseat of the Neon... considering the fact that it was a FWD Four Door (not coupe) car and essentially had a wheels on a straight axle dragging in the back... yeah.. they could afford to allow more room in the back. Aside from that... as a driver, I don't sit in the back seat... as an enthusiast, I don't want the extra weight back there anyway.

And... the Neon SRT4 wasn't without issues either... the boost fluttered under WOT creating what some referred to as the "Horse Laugh" sound... compressor surge was a problem on stock SRT4s. SRT4s weren't immune to transmission issues either. The shift selector and fork were prone to breakage... actually very prone to breakage. The tranny would grind from 1st to 2nd for many owners. If you owned anything earlier than a 2005.... forget about LSDs. Blown engines on an SRT4 isn't exactly unheard of either... in fact, you didn't necessarily have to mod them to get them to explode.

While I do understand that your individual mileage may vary... if you look too hard at any car, you can find faults. I'm happy that you were very lucky with your Neon SRT4 and you didn't have any issues. I'm not sure that every SRT4 owner can relay the same experience. Mind you, I'm not dissing on the Neon... just pointing out that sometimes we look fondly back at our past cars and don't remember the frustration and pain they put us through.

I'm not even remotely sure how one would go about accidently throwing the car into reverse going from 1st to 2nd (see picture below)

I bought the car because I wanted a new platform and experience of driving, as well as a newer vehicle. My GC is my first straight engine, RWD vehicle. It is a fantastic GT car, and I love it. It has amazing looks, is super comfortable and has tremendous potential.I have already seen the potential, now that I am bolton's and SFR tuned.. But the transmission IMO has been the single biggest issue with this car. Seems like every other thread I read was something about notchy tranny, grinding into 2nd, 3rd, even low speed grinding while granny shifting, grinding into 5th... and even me, I appear to be the ONLY person ever to have a transmission rear oil seal leak. And I bought it like that without realizing. But Hyundai didn't want to cover it, they told me they would replace the whole transmission and it would cost 5 grand because I had a short shifter installed. Whatever, Hyundai. Thanks.

Maybe I AM spoiled. I come from an SRT4 that had very little problems. It pulled hard, had no wastegate rattle or any weird noises, had a smooth transmission with buttery gears and even had 4 doors to comfortable seat 5 people in the car with no trouble whatsoever. Also, it was far, FAR faster feeling, even in stock form. Like I said, maybe I AM spoiled, going from a bolton's+tuned SRT4 making 320whp+ and 380wtq+ to a stock car. It was frustrating, almost. But I wanted a new car, with a different drivetrain setup, with a completely new experience. I am not new to Coupes, either. I owned a Scion tC. But even that had better backseats and a huge trunk/hatch.

To address your confusion on missing 1st to 2nd shifts:
Every manual car I have ever owned has been a 5 speed, and the Reverse gear was far right-down. The first car I have ever driven with a 6 speed transmission, and reverse being far left, up, was my buddy's FRS. And it had that handle you pull up to go into the R slot, otherwise it's locked.

So I'm still used to dragging along the wall of 1st to 2nd to shift, but now there is this notch there, and when you do it too fast/with too much force or without being conscious about it, you fall into the reverse slot and miss the gear.

So that's how that goes.

And yes, for my standards (Everyone has a different opinion and perspective of this) the GC is heavy as hell. Like I said, coming from my SRT4, which had a curb weight of only 2900lbs, this is a huge difference. That's a 462 pound difference, and weight has a huge impact.

Overall, I love the car. Always have. That's why I said all the things I said were just small nitpicks. They're not deal breakers. This car has tremendous potential and I knew it when I bought it. Once I modded it and tuned it, it feels closer to home like how my SRT4 was and it only makes me much happier owning it.

Yes my SRT4 was like that first love and everything feels like a comparison to it... But I've moved on, lol my new baby is badddddddd

GenCoupeGeek Uh... okay.

The Genesis Coupe BK2 2.0T comes with 274 HP stock with a curb weight of 3362 lbs. In the same model year, the Mitsubishi Lancer EVO came with 291 HP stock with a curb weight of 3516 lbs... and the Suburu WRX with a curb weight of 3208 lbs.

So... when looking at similar engine displacements and size... the Genesis Coupe falls right in the middle of the pack.... so not really sure what you mean by "heavy as hell" or painfully slow" given the fact that most cars in this particular class are running mid 15s to low 16s. While both the EVO and the WRX have faster 0-60 and 1/4 mile times than the GC, much can be attributed to the fact that they are both full time four wheel drive and have much taller gearing.... spinning ain't winning... and the combination of 4WD and tall gears means that they both launch much faster off the line and can use 100% of their power where any RWD car has to feather the start to keep the wheels from spinning. If you want to experience "painfully slow" test drive a Toyoburu FRS or BRZ.

There are very few coupes that have a usable back seat. Even a far larger car like the Mustang has a back seat that is good to throw stuff in it... but not for people. The exception to that rule may be the Dodge Challenger... yanno... if you don't mind lugging around 4,500 lbs of car.

Wastegate rattle on an electronic wastegate is nothing new. I think the concept was invented by BMW... who has been plagued with wastegate rattle since 2006. Unfortunately it's kind of the nature of the beast. If you do a Google search on "wastegate rattle" you'll find the first page and a half hits go straight to BMW pages. Sorry to say, Hyundai didn't invent this particular issue... I'm pretty sure the German's did.

I'm not even sure how to address the "shitty manual transmission" comment because I don't find that to be true on my 2013. Now.. that may be just a matter of perspective as I've been driving manual cars for over 3 decades now and I am very familiar with just how "shitty" manual transmissions can be. Have I driven better? Yes... but I can tell you that I've also driven far worse.

Now... with all that said, Hyundai built a car for the masses.... not for the enthusiast. They included a LOT of stuff that would appeal to enthusiasts, but they don't charge more for it. In 2013, a Mitsubishi EVO sticker price was about $36,661.00. A 2013 Suburu WRX $29,295.00. A 2013 Genesis Coupe R-Spec $25,294.00. Given the fact that the price listed would buy you a stripped down EVO or WRX vs. the GC R Spec with a list of features that both Mitsubishi and Suburu would charge extra for... I'd say there's a pretty good value for a decent GT car with lots of potential.
