So much incorrect info here... while dinan does cover your warranty issues it also does not really boost your power of the car by a lot that's why they can give you warranty.
Price for dinan cost thousands of dollars more vs the Competition.... a simple piggy back will not harm anything as others have tested including me and only cost $400 while dinan for less performance charges 2k +
