Brake boosting vs launch control

dk79 · 01-06-2019, 01:35 AM

Has anyone tried manual brake boosting vs launch control with racechip?
I have bad luck with wheel spin at drag strip everytime using launch control no matter what the rpm is at launch. Have stock Michelin tires.
Was wondering using brake boost and launch at 2k rpm might give less wheel spin and better 0 to 60 and 1/4 mile time.
My best is 11.1 at 129mph with racechip.

Use the JB4 to reduce boost in 1st gear based on track conditions. Launching off brake boosting can be hard on the car and may trigger a false alarm accident warning code.
