VEC-1 - any documented improvement in 1/4 miles as a result?

[dwhitt]

Trying to get from 12.30's to 11.90's and thought I would explore this angle. My mph seems low at just over 116 mph. Not sure why it is off? Are the VEC-1's difficult to tune?

Mine made over 20 RWHP with the vec-1. You need to have it tuned on the dyno for optimum gains.

Get your car dynoed... if it is above 400RWHP, and you are still getting only 116mph, it means you are shifting way too slowly.

When I shifted quickly, MPH was 120-121mph on a basically stock car (414RWHP). When I shifted badly, it would be 115-117MPH.
