Never a problem at the dealer, even though I'm completely out of CPO warranty. OP - congrats on your upgrade, and enjoy! And as far as the Dinan-knockers on here - "Illegitimus Non Carborundum"!
Roundel, did your car come with a factory OC or did you buy an aftermarket one? I ask because I currently have Stage 1 Dinan and want to upgrade to stage 2, but I am trying to avoid paying $1500 for a factory OC plus labor and the additional cost of the stage 2 upgrade. If you have any advice for me I would appreciate it!
