how high do you rev?
i have a stock 5.3 motor right now, just hypertech programmed. i set the limiter to 6300 and the shift point to 6200, it screams that high in second gear, but it actually makes a BIG diffrence. Any one else do something like that?

According to the hp/tq numbers of a factory 5.3L peak hp is made at 5200RPMs. I have mine shifting at 5800RPMs (approx 38mph on 1 - 2 shift) and rev limiter set at 6000RPMs. I've played around with the shift points setting them higher and lower and setting the shift points 5800RPMs is where I get the best 1/4 mile times.
