They are both great tuners, flip a coin. I went with Madz28 because he was a little cheaper and local to where I live.

 

I agree, You can not go wrong with either one.

 

id say go with PCMforless. brian would be doing your tuneing seeing as your a 97 car. he lives locally around here and is a wonderful guy. but you could always just e-mail both and see who shoots you a better offer.

 

Here's another vote for PCMForLess. I've personally worked with them and have experienced nothing but the best in terms of everything. Customer service it top notch, completely willing to help with issues, and the tune can't be beat. True professionals, both of them.
