those numbers are horrible,may need to properly tune the car.Not to bust your balls but my gn with only a k&n filter,chip and 2 1/2 exhaust system i ran 13.60 all day long 6 years ago.The rest of the car was bone stock.i would say with your combo you should be at least mid to high 11's.How much boost due you have it set at and how much boost are you leaving at?
