My speed limiter kicks in at 96 on the speedo which is 94 on the GPS.
The rev limiter is 5400? I've been wondering what it was and don't really want to find out the hard way - at 5200 it's making enough racket! I don't have a tach - I used the diag mode on the odometer once to record RPM's and used math to calculate it out.
Actually, there is no reason to push a stock 4.2 past 5 grand - that's where the power really starts dropping off and it sounds like ass. My only mods are an Amsoil air filter and a cheap low restriction muffler which sounds like rice at high rpm's.
