I'm gonna go w/ everyone else and say you need to set a REASONABLE ET goal... or if you really want some power; get boosted!
i'm guessing you have a differnet 5th gear as well; z6 tranny isn't gonna make it to 130....My Concerto does 130+ on the speedometer with ease and it's 150-200lbs heavier. And that's with a sohc non-vtec zc. It does have a gearbox that's a tad shorter, I'm at the redline at that kinda speed.
