The truck feels and sounds like it has a big ole cam in it. Shakes real bad too. Also how do i use the idle up feature? Sorry for so many questions, appreciate all the help.

Part number of tuner is 159402, checked with the tuner if there was any codes and there wasnt.

Put the Extreme tune on it today and it still did the same thing, returned to stock , tried the economy tune still does it.

I bought a predator about 1 month ago truck was fine before i put it on. I put on on the performance economy tune and all of a sudden my truck hunts or surges when decelerating (sometimes real bad) and when at idle. Makes my truck sound like a bag of poop not to mention is dangerous.

Anyways return ...
