You've got my exact setup minus the boost controller. I just have the JWT ECU jets for the 14/15 lbs boost. I too am only pulling 2.15-2.25 60' times w/ the stock torque converter. But my trap speeds are in the 109-112 range giving me ET's of high 12's - low 13's.
You may be loosing boost somewhere.
