This started yesterday. When I'm driving normally the truck will buck. By that it feels and acts as if you were driving along and put the truck in neutral with out letting off the accelerator then dropping it back into gear. It will do that 2-3 times in succession then be fine for while. Its in the upper 80's here and the tranny is running about 170* I have no codes showing from my sct which is about what I expected. No flashing lights either. I haven't messed with the tuning since probably september of last year. It has been set to hybrid race. I did change it to a tow tune with the same dropping out of gear then to stock and it still is doing the same. My guess is a wiring issue but I kinda wanted some reassurance.
