Like my 97 SE, your PCM stops the fuel injectors at 108; hence, you can't get over about 2000 RPM at that point. This is a soft limit that can be reprogrammed, but I've heard in the past (source forgotten) that going over 120 or 130 may allow Bernoulli'* principle to lift your front end off the road.

And as always, to everyone, test this out at your local Bonneville Salt Flats, not on public roads. Petition your Congressperson to bring the BSF to your state.

FYI only, When you approach the top end of the speed limiter and back off a little and smoothly acclerate, the speed limiter will be over ridden. She can do a little better than 150 before the RPM limiter shuts her down. And yes Z the floating effect does kick in and ateering is loose as on ice. That said, I locking this thread. It is old and on a line we prefer not to cross here. What you do in your time as far as legalities is your business. Not allowing it to be discussed here is mine.
