i seem to get boost too soon i think. I want to take off with min tire spin but even at 5-10 mph start and I punch it it spins out and the track light comes on too doesn't that kill performance ?

Do the reverse of the BCA adjustment in Techinfo. Good luck, though. With a belt drive, a SC is intended by design to produce boost and torque right off the line.

I'll move this to Forced Induction for you.

If you'd like less boost.. sell me your pulley.

My suggestion is to disconnect your wheel speed sensors to prevent torque management in the PCM from pulling timing, and manage your launches yourself. This may mean better tires.

I can lay insane amounts of rubber down if I want to, even with my tires siped. But I can also control my launches perfectly without traction control and with nothing more than a chirp.
