The car is a 2000 Pontiac Ram-air, it has a 408ci, patriot stage 3 heads, Texas Speed Giant Stick cam, Fast 90 intake and 90tb, custom 4in maf we built, 4L60E trans with a Precision Industries Converter. Ok Ok I have the car running and driving great, wot is perfect but on the dyno and street the converter @ 5500rpm just come unlocked. Im trying to figure out if I missed something in the tune before I pull the trans and send the converter back. The car made 480rwhp @ 5500rpm when the converter comes unlocked, and the pull is straight up until then so I know this thing is goona make some decent numbers. Let me know if you see anything. Thanks for any help you can provide.
