what am i doing wrong?

It'll pull strong up to whatever the dyno showed as the peak hp. You should be a little above that going thru the traps. You might even want to try shifting it a little higher and check your timeslips. Try going up a 100rpm and see what it does for your et. The dyno tells you what the engine will do by itself on a stand, once its in your car you have all kinds of other variables that will affect your et. Thats where the engine and chassis tuning comes in :roll:
