Have a low top speed launch in 1st and add weight
Vague but basically what you need to do. Add full ballast to -50(front), flip tranny to stretch lowest top speed to 135-140, and make sure your launch doesn't hit rev-limiter. Takes a while but, when set up right, you can drop .2-.3 off your times at SSRX with little tweaks.
No. Its best to let launch hit red limiter but not bounce on it.
