Hey guys, new here and new to the Duramax.. I bought a 2016 Denali 150k miles, PPEI tunes, 5 position SOTF
Fass fuel system, S&B intake..
of course it felt great in the test drive, after driving the truck a while I’m noticing a skipping or inconsistent pulling if the truck is under a slight load form 3rd gear on in pretty much every tune.. feels like a torque converter not locking up maybe? Anybody have any ideas? Before I go throwing money in all directions.. I have new fuel filters on the way, just to try something.
