yesterday i topped out my grand prix. only 124 MPH. I have a 5spd 4 gear went all the way to 110 MPH i shifted to 5th and at 123 or 124 the computer shut off fuel. i could of easily hit 135 MPH my RPMs were only at 4,000 when it shut off. What do you guys think. I need a performance chip will let me max out my car.

I didnt know fuel would shut off on a manual. Anyway, a chip should take care of the fuel shut off. http://www.fastfwdperformance.com makes 3.1L chips and you can set your own speed limiter. But I really didnt think there was a fuel shut off with manual trannies

Yeah, my 89 CS getrag has the same 117 speed limiter as the auto version, but no rev limiter...
