SFR Reflash 0-60 mph

I see that with a SFR reflash on the 3.8 6 speed...the quarter mile is on average 7/10's quicker. Does anyone have results for quicker 0-60 mph times?
Thanks

When it comes to tuning a car, there are multiple things that are changed. You have canned tune which is a safe tune that is a pre set tune for everyones car. Then you have a custom tune which is changed upon your car. Every car is different, when your car is being tuned the timing is changed which allows your car to be brought to its full potential. Yes your 0-60 time will be faster but on a naturally aspirated vehicle the gains wont be compared to a turbo, supercharged or a pro charged car will be.

If you're after 0-60 times with a tune, you're doing it wrong. You're lucky if it translates to even half a second, and driver skill is still the most important factor.

After all of my mods, SFR put me at about +30 whp on a mustang dyno.

I haven't tested the 0 to 60 time specifically sense getting tuned, but what I can tell you is that the car is definitely a hell of a lot more punchier.

I've had some recent problems, where I had to put the stock ECU back in (completely unrelated to the tune) and the first thing that I noticed is that the throttle maps on the stock car suck complete ass. there is a weird thing going on where the pedal does not respond accurately to how you're pressing your foot down on it.The tuned version, is way more comfortable to drive and accurately control your throttle especially in the middle of curves, where precise throttling is required.

I would get the tune, for that alone

Well said.

It seems the 3.8 and 2.0t both have this issue. I had the same experience (throttle unresponsiveness) when I put back on the stock ECU for yearly emissions.

A tune really smooths out everything - no unevenness with throttle anymore. That's the biggest benefit for me but, then again, my goals were never to drag the car.

I didn't realize it was so horrible until after I got the tune. I drove the car for about a month on the tune and even tracked it, and fell in love. And then when I took it back off, I thought something was seriously messed up with my throttle. but others confirmed my suspicion. it's like they tried to dummy proof the car and made it so you have to press down extra far in order for it to do anything, but then when it does do something it jerks and goes too far because you stomped your foot down.

I just broke apart on my car and I'm waiting for the new part to come in. I can't wait to get this car put back together, drive it for another week to make sure that nothing weird happens, and then put the tuned computer back in

It's a fair question. I think the .5 second difference can be significant if you're going from the "stock" 5.2 second time down to 4.7. It'll make for a couple car lengths difference in front of a similar, but untuned car.

Fwiw, my 0-60 with just the r2c cai was 4.9.

I'll have to test again with the tune after I solve these other issues.

First gen 3.8 M/T with R2C intake with Hex Filter, Ark down pipes, test pipes and grip exhaust with an SFR Dyno tune. My 0-60 has seen the lowest of 4.5 seconds after the tune. I average 4.8-4.9 when I'm just messing around, if I try hard and focus on perfect shifting and a great launch I can almost hit 4.5-4.6 seconds every time.

Umm, I don't mean to be "negative nancy", but I doubt you wil get .5 gain 0-60 and .7 gain in the 1/4 mile on tuning a stock naturally aspirated car. Maybe on an already modded car with bolt-ons.(non turbo of course)

Those gains are normally associated with almost a 100hp gain! Most tunes yield about 5-8hp.....

Turbo car tune can yield those numbers.

I hear a lot of people saying that the tune doesn't make that big of difference for the 3.8. My SFR 91 octane tune made a huge difference for me. The peek HP and TQ numbers may not go up as much as the 2.0T cars but the car pulls harder with less lag all the way to red line. I can't tell you how much quicker the 0-60 is because I want to keep my carrier bolts in one piece but you will definitely notice an improvement.

I switched back to the stock ecu to take my car to the dealership. I need an oil change and want to ask if there is any way in hell they will do a ring and pinion swap for me. Driving my car with the stock ecu reminds me just how bad the stock tuning is on my 3.8.

custom tune for 3.8 makes a major difference. I don't care about 0-60 or 1/4 times (i'm a twisties man), but I can tell you there is a difference. It's unfortunate that the N/A motors don't find as much gain in the TQ area as a F/I motors, but that's the nature of the beast.

I just got my 2015 3.8 MT custom tuned by SFR last month. It feels much more responsive. There's no more lag in revs after modulating the throttle. I suspect the 0-60 time is improved significantly considering the torque gains throughout the entire rev-range. It makes sense looking at the low, from 2500-5500 rpm gains range from 20-40 ft-lbs. Also got rid of the annoying fuel shut off issue by raising rev limiter to 7200 rpm

I have R2C intake, intake manifold spacer, CNT V3 exhaust, and running 87 octane. (80*F). Best bang for your buck mod in my humbled opinion.

youmust live in one of those states where the cost difference between 89 and 91 is more than a dollar. Thankfully on the west coast it's only a $0.10 gap between each octane rating.
