I dyno at 177hp/155tq at SZ06 (which I thought was pretty decent)... A year ago I run a 15.4 1/4 mile. I go to the track this weekend with new mods including headers, opt'ed Y pipe, koni sport suspension, RSTB, subframe connectors... I was hoping for a 14.999, but Nooo0o0oooooooooo!!! I'm stuck with a consistent 15.2x... After 3 or 4 15.2x's I became frustrated and the times started dropping 15.3x... 15.4x, then I called it a day. I want to be able to get into the 14's N/A and without a 3L, and I've done just about every supporting mod. What can I do to obtain a 14.999 or better?

Rant off...
