back to stock issues

[sffd19]

Hey All,

recently went from supercharged back to stock and now I'm having some issues. Car stumbles and hesitates at low rpm and steady throttle. Has a P0300 code in freeze frame data. Car ran perfect with the blower but now I'm pulling my hair out trying to figure out what the heck is going on. Vacuum leak maybe?:shrug:

Back to stock tune I assume?

Yes. Went back to 100% stock then just for the hell of it I put on my jlt intake and loaded the tune I had for it. Same result. Bad stumble below 2500 with steady throttle. Then when you get on it it's fine.

By chance don’t you have to change the plug gapping going from forced induction back to N/A?

Turns out my charge motion control magic was malfunctioning and causing my issues. I forgot to scroll down and look at all the codes on my scanner....
