T72 got full boost at 3000rpms with Phamspeed kit
Full boost off the wg spring (5psi) came in right around 3K rpms. This was done mostly in first and second gears. I'd say 10psi should kick in right around 3200-3400rpms. Very responsive turbo!! Lag took away some low end but still pulled hard in any rpm we stomped on. Trending Topics
