emmm, I went in to limp mode on my tork tune, it triggered a pending code but didn’t sent a check eng light. So check codes with a OBD2 scanner first. Keep in mind there was a pending code but NO check eng light yet.
It turns out my car was having some spark knock around 4000RPM. I clear the code and used a bottle octane booster it went away and never returned.
Check fuel quality
The bump might sent some stuff off you never know
