For those of you with VB re works from Don Cooper or Level 10, how much will it improve for the 1/4 mile, whats the feel in everyday use like slow driving etc. Im about to do the job with Don. Thanks

 

Haven't ran the 1/4 mile at the track, but I can pull consistent 15.6 with my G-tech (intake and muffler). It'll shift harder for each gear, but not so hard that it will jerk your head. The VB is a good investment IMHO. Go for it.
