Makes sense. No, I haven't used on any other vehicles. The only thing that has happened out of the ordinary since I've owned the chip is its been reflashed by Ford...but it was returned to stock before they did this. Additionally, I had a mojor problem trying to do a cold start with it firing up. Tomorrow morning i'll see if the cold start is still there...if it is, as far as i'm concerned I wasted $100 on doing something I could've done myself.
