I still don't believe there is a proper fix for this including replacing the ext harness with a newer (upgraded) one from Stillen. Very annoying and unsafe!
Limp mode is where the car has almost zero throttle. That's not the symptom I'm having. I'm having a symptom where the car idles above 1k and won't rev past 2.5k.
