Installed the Diablo Chip from Amazon Racing today. Words cannot describe. I never thought SOTP results like this. I'll dyno next week but I got to tell ya, I'm having to learn to drive a whole new car. That sorry ass shift light is gone. WOOHOO....I was under the impression that the TC would change to ON for default. Anyway Thanks a ton RICK. I just didn't expect such a difference. BTW it helps to follow instructions!!!!!
