I was thinking of the total removal and then install trick myself, but now with what we all just learned in the other 3.7 to 5.0 thread I hope I didn't mess anything up by immediately tuning with 5.0 tuner instead of tuning with 4.0 tuner as an intermediate step. It would have been nice to be properly warned and instructed to do such, if that is a must do before one goes ahead and messes up their valuable data. I can follow step by step instruction....
