Hey guys, I've had a couple instances of the car stuttering and stammering at WOT. It happens at low and high RPMs and most of the time within a second or so of going to WOT. I just put the JLT on the car a couple weeks ago and haven't had a chance to get it tuned. This is the only problem I've got, no rough idle, no stalling or anything like that. I need some help folks.
