Transbrake and building boost
First time user of a transbrake, trying to figure out some of the features...with a turbo car, can I start building boost as I footbrake the car into the pre-stage lights and bump into the staging lights using footbrake, then engage the transbrake? I don’t seem to have enough time once I’m in the stage beams to build boost off just the transbrake, and not really wanting to get a 2step. I just didn’t know if you can transition from a footbrake to transbrake while building boost around 3k, without tearing anything up. It’s a built 4r70 with circle d 3400 stall, mvb, and pa performance transbrake. Thanks!
