All of this has me torn a bit, on one hand I'd like to find the max power of this engine/combo. And on the other hand I'd like to not have to work on the truck next summer and enjoy it.

Like to take it of the Car Craft National next year and that can't happen without solid reliability. Lot of empty miles between here and there. So I might finish the tune and then back the power off by dropping the boost to 10 psi.
