Tuning a modded car? What tuner?!

After doing a lot of research on tuning, i cant seem to find the info that i am looking for. Im getting a plan together to do a gt30 top mount on a 2.0t. What kind of tuner do i need to support the modding i will be doing? or can i just take it to a tuner and have him give me a tune on a dyno with the stock ecu and no aftermarket tuner on it. I built an lsx n/a car and i just took the car to my tuner and after he was done it was good to go. Or can i just send the ecu out to a company tell them my goals and mods and have them put a tune on it? Personally i feel more comfortable with a tune from a professional on a dyno. If that is the case does anyone know of any good tuners around Indianapolis, not opposed to driving a little ways either. If i need a tuner or cmd or something like that, what is the best one? I see a lot on haltech and cmd, still not really sure what the pros and cons are to either of them. Thanks for any help.

Not just any tuner can tune a Hyundai ECU. Any competent mechanic should be able to do your hardware install.

Tuners that can tune your ECU and just so happen to be vendors on this forum: BTRcc, SFR, BR, and TurboXS. There's a handful of tuners out there such as Piranha Racewerks who also provide competent tunes but are not vendors here. If I didn't mention anyone else, it was on purpose because you will not be happy with the tune you get and could end up with a windowed block.

Now, the problem with your plan is that if you are not using one of the setups that are provided by one of the aforementioned tuner, you will most likely require a custom tune on a dyno as you mentioned. The problem at this point is that you will either A) Have to pay the tuner to come to you, B) wait for a tuning event to come to you, or C) Drive your car to a tuner to have it tuned.

Option B: Spend the money and get a Haltech PnP ECU. The Haltech can be tuned by any competent tuner; however, keep in mind that tuners outside of the Genesis community do not know the specific strengths/weaknesses of the Theta II engine and will most likely tune the car minimally to keep from blowing it up. I know some of our vendors are working with Haltech to eventually offer remote tuning (you provide the dyno and they provide the tweaks in near real time); however, no such solution currently exists.

Option C: You can tune with CMD. Just know the risks. More cars have been blown up using CMD than any other tuning method known to man. The problem is that in order for CMD to do it's job, it has to lie to the OEM ECU by sending it data it expects to see rather than actual parameters. This means that it is very easy to over ride a safety feature intended to protect your engine from a bad tune and blow it to pieces.

+1 for Beyond Redline. Their customer service is great and they are great at helping you out with what you need and what you don't need. Tim is great to deal with and I plan on continuing doing business with them. They have tuned plenty of high horsepower Gen Coupes.

I'll throw a +1 for TurboXS. Jermaine tuned my custom GT30 setup and it runs VERY well. I hear good things about Beyond Redline too, but I don't have any personal experience with them.

EDIT: TurboXS has FANTASTIC customer service too. Raj is the man.

Did you drive up to Maryland from Orlando to get tuned?

No, I put together a tuning event down here. Raj and Jermaine flew down and tuned a handful of cars on the dyno. Jermaine worked very diligently to make sure everyone's tunes were pretty spot on. Super cool dudes.

Cool... I'm thinking about getting a custom tune from TXS to see if I can tweak a little more power out of this stage 4 kit. Just about every big number tune I see come out of TXS keeps wtq down while pushing some pretty impressive whp numbers. I haven't seen where any of the other tuners have been as successful at doing that.

I don't mind the lower tq numbers, as I was originally building the car for road racing anyway. Plus, the added benefit of reducing the chance that I'll spin a bearing or window my block is a major plus. I have had the car tuned since April of last year, with lots of full boost time, and even one track day, and she has held up great.
