Question on acceleration...

What are the "sweet spots" and the "weak spots" of the 335's? MPH wise please... i notice at certain points my car pulls hard and at other points she lags but i'm not able to pin it exactly yet....

A vehicle will accelerate the hardest at peak torque. Conversely, it will accelerate the slowest at torque valley point. The peak torque seems to be around 4k revs with most of the current tunes but hasn't always been the case. Just look at your dyno plot and see where min and max torque occurs.

That said, the above is only relevant for acceleration in a single gear.
