try to find the right rpm to launch at, and the right boost presure. with my experience, i launch at 3300 rpm, and can't have my boost above 14 psi in 1st. any more rpm and i hop, and any more boost and i'll spin the tires after 5500 or so (t-25, not bigger turbo). and listen to 95gsxracer about suspension, and all of us on tires.
the remote switch goes on the steering wheel. on GReddy electronic boost controllers [profec b; b spec 2] there is a lo and hi boost setting, and the remote switches between the 2. the remote itself can't hurt your car, but the boost levels you switch to might
