Suggestions for tuning a '97 Vette Before I get "kicked out" for asking such a basic question, let me give my background. First, I mostly hang out in the Transmission section, answering 4L60E questions every day. I have a heavily modified LS2 swapped into an '81 Camaro and am very comfortable with HP Tuners - I have experimented with nearly every table and change something every week. My profession is computers and my other hobby is electronics.
Now my basic question - I have a friend with a '97 Corvette that he wants to hot-rod a bit. He currently has a cat-back exhaust, EGR removed and would consider headers and removing the cats. (In Michigan we have no emission testing. Yeah.) I am willing to spend a little time changing the tune, but don't want to spend many hours logging and modifying/smoothing the VE and MAF tables as I have done with my own car. So the question is - what minimal changes and tuning will give us the most bang for our buck and time? Lets say a budget of $500 and $1000. (Please don't suggest a converter - I'm not keen to swap a converter on a Vette; we are looking for HP, not lower ETs.) A cam swap is more than we want to do now (although I have done several myself).
Also, are there any tunes that improve performance on a stock '97 Vette? I couldn't find many '97 tunes in the HP Tuners repository. Or recommended changes to the timing or other tables if emissions are not an issue? If later model tunes work better, I know a '99+ tune won't load into a '97 PCM, but I could hand-enter the relevant tables.
Thank you for any suggestions and I apologize for such a basic question.
Ted.

I thought this was going to be a simple question; perhaps not.
Heck, I could swap to a 2002 PCM if people think that would make a big improvement. (I have tuned both '98 and '02 PCMs.)

Thats why I said they are the same, because you can flash them to either one. Just like 99-02 pcm's, there are different service numbers but you can interchange the pcm's also.I didnt want to post up about service numbers to make it even more confusing.
