I'm not saying that with SD it wasn't possible to squeeze a * or two more timing out of it or a psi or two of boost - maybe leaning it out a bit (all make power) but if nothing changes its impossible to make more power.


sorry i went out and clarified it was 1 more psi, still help through redline, also 1 more degree at peak torque, and 2 more degree at redline, and better fueling, it was leaned out more this time about .2 across the board. so i can see where the power came from, it just seems that with SD it was easier to get these changes in
