Ok so after installing prc stage 2.5 heads torquer3 cam fast102 and ptm throttle body and 36# injectors I have gotten a mail order tune from Texas speed (3 times now) and I'm still having issues. The car won't start without having to hold open the throttle and walking it down to idle and if you give it any power when it comes down off the rpm's it stalls. Normal driving is ok for the most part except the trans bucks while in overdrive. Does anyone have any ideas as to what could cause this or know someone in the Waterford Michigan area that knows how to tune this thig in better than these guys at Texas speed?

 

So many people need tuning help and no one ends up being around my area go figure. You need someone to dial in your cruising cells and play with the throttle cracker and follower settings. A mail order tune isn't really a tune. It's good enough to get you to a tuner who can look at the car first hand or to a dyno.

 

Wrong forum.....

 

I am amazed that TSP even gave you the 3 tunes.

As above a mail tune is to get you mobile, take it to a tuner & get it tuned properly.
