i am at my wit's end No one can tune my car. It is an 02 WS6 with PRC stage 2.0 5.3 liter heads with an F11 (112 LSA) cam with all the supporting bolt ons. Long story short, I have been to three different shops, and at $400 a pop, I'm severely disappointed in my results, and I've actually contemplated selling my car.
The third tuner got it the closest. He showed me the ridiculous "tunes" that the other guys charged me for. He picked up 30 rwhp and 30 ft/lbs with basically no changes to the car, and showed me where most of the major tables were untouched by the previous guys.
But, my car STILL tries to die when I come to a stop, push the clutch in, or put it in neutral. It will fall to 300-400 rpms and kind of hang out there for 7-10 seconds. It will sometimes find it's idle, and then it will sometimes die. If the a/c is on, it will die almost every time. I can't drive the car like this.
I called the third tuner, and he has moved out of state. I am wary of mailing him my PCM for obvious reasons. If I find another tuner that I actually trust, I am out another $400, which brings me to $1600 total just to get my car right (maybe). I'm out of ideas. Is there anything I can do for this problem without taking it to someone else (tb drill mod)? Am I stuck buying the software and trying to fix this myself?

It just sounds like you need to push the base running airflow tables around alittle. Its sounds like the rest of your tune is good. You can buy the software, and mess around with the idle tuning until you get it the way you want it, then sell the software and get most your money back. And that way, you can do it at your own leisure. You really don't need a wideband for idle tuning (I think).
What kind of throttle body do you have?

You can't sell your 2002 SOM WS6 M6! What fun would that be? How much time did each of these tuners spend on the car? If you're ever in AL let me know. I've got the licenses for 2002 and I've been tweaking on my tune for years. Do you have the file of the tune by any chance?

It just sounds like you airflow tables need some adjusting, There is nothing you can do without software, well the only thing you can try is to open up the TB a tad, but this will change your IAC counts and without knowing if they are too low or too high. But its worth a try until you can get it to a reputable tuner..

Dude, I feel your pain. I am not far from Lawrenceville, thats where my family lives. I went to four shops that claimed they were LS Tunners and performance experts.....WRONG. After 7 months of looking I was finally turned on to Vengeance Racing and I have NEVER looked back. Give Ron a call and they will take care of you!!! It is just a short drive across 20 to cumming, you will not be disapointed!!!!

As far as I am concerned, Vengeance is the only shop... period. There are still quite a bit of wanna be LSX performance shops in Ga. All of us in the area are very fortunate to have one of the nations top LSX performance shop so close!!

If you can get your car to Vengence that is your best bet. I am a couple of hours away from them and it was inconvenient for me to haul my car there. I e-mailed Vince at Trifecta. He has a tuner that can record your program while the car is running and you can e-mail it to him. He will see what problems there are and correct it. He just did mine and did an awesome job. I think they are a sponsor here. Tell him I said hi if you contact him.
