x2; it's not just that the 60-ft is soft, but something is holding it back from making the power needed to be closer to 10.0s. "On paper", you have the potential to make more.

My car went 10.5s at 126 w/ 1.45-1.46 60-fts. Even if I can improve the 60s, I'd expect it'll still need the HP to run 130++ to get down to the LOW 10s like you & I both want.

Dwayne told me recently the step from 10.5s to 10.0s is going to be a big one, much harder than what it took to go from 11.0s to 10.5s, so I'm right there w/ you.
