Still wouldn't run one. The some people have good luck with them, but the majority of customers have issues. If I am gonna pay X amount of dollars for something I want it to work right the first time. NOT...F-O-U-R times.
Just get a DHP PCM or have someone tune your car around the area that deals with the 3800 platform. You can get them @ 3800 Performance - high performance aftermarket car parts for your Grand Prix, Monte Carlo, Impala, Regal, Bonneville, and V6 F-body!!
gotboost3...do you have a 2003 by chance? I have a '03 DHP PCM I would be willing to let go. PM if you want.
but the thing is that all the shops around here ive heard a lot worse things about there tuning services than anything ive heard about ZZP
