I put a stiffer spring on the wastegate and re-set it. MAN, what a difference! Watching the DP gauge made it evident that before the pulses would blow it open during spool up, I can now see about 7-10psi of quick fluctuation where before it was decently steady. Spool up is a lot quicker and I can blow the rear tires off in 2nd and 3rd from a 25mph and 45mph roll.
This is where I currently have it set.
