Though I have the MST BTM6 with boost retard, its in a drawer until a later
date. Without a wastegate, I monitor boost with the boost gauge and back
off a bit if boost goes over 10lbs. I've filed a needle that leaves me rich
under virtually all conditions, but most especially at high throttle
settings. I burn only premium, and for a fun weekend drive, I've begun
adding toulene as well.
