Ok 3.0l 82mm turbo motor and we are flashing the converter on transbrake with a 225 shot but it's flashing too high 7100 rpm, 42 lbs of boost(380kpa), and 225 shot are leading to 200ft burnouts. Without nos the converter on transbrake goes to 3000 rpm and does not make any boost. How can we limit rpm while being on the transbrake besides not flooring the car or just launching right away. The goal is competition drag racing and we need consistentcy and having the ability to adjust the two step/ three step limit. Any ideas ? Ecu is a motec 800

Thanks ,

Have you tried a 2 stage rev limit with the transbrake as the trigger for the 2nd?
Maybe the overrun boost enhancement upgrade used in rally would be useful to hold boost at the line?
Running a multi-stage NOS system sounds like an option.
