Oh... Yeah....
Put the stock map back in there. Your IPR duty cycle base map is WAY too high at an idle (3-4 MPa). Big oil should love that stock map!
The thing that really bothered me about "brand-x" tuning was the IPR duty cycle would cause a HUGE dip in RPM once the transmission downshifted and the engine dropped to an idle at 35 MPH. This was simply due to the high IPR duty cycle and the lag time required for the PCM to decide that the base duty cycle was way too high to maintain 600 PSI once the RPM dropped quickly.
Put the stock map in your programming. Your truck will thank you.
