This comment isn't meant to slam ADC or any other vendor that works hard to help us out. However, when it comes to chips for YOUR car, the best solution is to take YOUR car to a tuner for a custom tune. Reason being, you car is vastly different than my car and trying to develop a chip for both is going to be a compromise. Not to mention, this process makes a lot of assumptions that getting a custom tune in-person will not make.
My advice: choose a chip maker, then look at their website for a tuner in your area. Call that tuner and schedule an appointment for some dyno time & tune.
Yes, it will cost more, but will get done right the first time. I can't tell you how many times I have seen people send in mail-order chips again and again just to get a marginal tune.
