I want to know how 7172 Duster and his buds are launching so strong! Those are very good 67 foot times. I am using a 3.91 and what are probably stock springs. Where would you guys look for improvements in the launch. Oh yeah, the converter is about 2200 RPM but works well on the backroads I drive at 45-50 MPH at 2200-2500 RPM so I would rather not change it.
Besides, I won't be putting in bars and the car is already too fast.
