So my problem is pre-detonation. It is strange because if I run the factory 241 software, the problem goes away. If I try to run the Alpine tune from Alex, I get nasty pre-det at low RPM and some pre-det at higher RPM when accelerating hard.
My plugs all look really good. The only strange thing I have on my car are the Dinan throttle-bodies that the previous owner installed. Intake is a Dinan filter assembly so that really should not change much.
Thanks for the help and I will try to get a video at some point.

Hi. Have you ruled out an exhaust leak? Might be worth to have a smoke test....coudl be a pinhole leak on the clamps.
