870 pedal delay/ throttle response issue

[DCtruckin]

I ended up taking the truck to Cummins to have them assess this pedal "delay". Turns out in the ECM the throttle was set to I believe it was "progressive" not automotive. they reset that and ended up putting the factory 550/1850 file in the truck and seams to run good ish now. I still need replace the turbo control air valve, I bought a truck with a yellow motor and am enjoying that too much so Ill replace the valve when I get to it.
