If you are happy then I'm happy for you. Their customer service is pretty good. I know, I've had to use it several times in the past couple years. I just got back two MK4's that had performance issues. Just make sure you check everything out yourself, even though they probably sent you a statement giving it a clean bill of health. I got one back from them they said was ok and it's adjustments were 10% off!
You basically turned it into a MK4 clone, nothing wrong with that if that's what you wanted. Like I said, it's your money and you're the one using it. I mean good grief, I've seen 4x4 trucks with ground effects on them!
