This is for people with the DHP pcm, i was wondering about how much faster can you go in your GT/GTP with the speed limiter removed... I know the gt tops at about 108-110(stock..97+) but for the gtp, dont know... so yeah max speed gotten from you crazy people..

Re: Max speed with DHP PCM!!!????
If the limiters removed, you should be able to break the speed-o for sure.
Top end would be what they read on the speed-o, if your tuned good, and everythings working right. remember safty first!

A lot of Grand Prix GTs and GTPs have a Heads Up Display (HUD) display with a digital speedo readout so you will be able to see what your top speed is beyond the regular analog speedometer.

Watch out for deer
I think I've heard gt's doing about 130-135. GTP's 145-150. |
