Im also very happy with my Whipple tune and CAI, by the way I have an extra CAI from Whipple as when I order it I got a good deal on a Shelby by Whipple CAI (the only difference is the badge that say Shelby by Whipple vs Whipple) if anyone is interested I can sell it for $300 (retails $375), I also have a Airaid filter to replace the OEM filter (used for 200 miles in like new condition) for $70. DM if interested.
