    Brake Boosting

    I cars cut throttle when trying to brake boost, not that we need it with the small turbos. I was just fooling around with it last night. Is there an easy way to lift this?

    Yes...

    stay COMPLETELY off the throttle, apply the break first then stomp the throttle holding the brake.

    I've tried it a few times trying to figure out a boost issue and once the boost hits about 2lbs, power cuts off and goes into vacuum and I slam on the brakes.

    You have to be 100% off the throttle before you apply the brakes. Once you apply the brakes you go full throttle and keep hold of the brakes and you'll have yourself a mighty fine brake boost going.

    A tuner should be able to calibrate this out. There are vehicle speed and engine speed criteria to allow this feature to function. You can set the engine speed limit to something like 10,000 rpm so the feature never activates.

    i have APR stg 3 software and i can brake boost all day, dont have to do anything special... just smash the throttle and apply brakes as needed to hold the car back, and this does help in racing sometimes.... i was racing a mid 12 sec regal one night and with having a supercharger and instant boost i had to brake boost so he didn't jump a car length on me right away

    its funny you say that, cause i have beaten a 10secS4 tuned s4 (not a big deal) and an ASP tuned S4... both stage 3... but they did not have meth injection... but me having meth shouldn't constitute the 2-3 cars i put on them :)
