Welcome! As far as tunes go, Trifecta has had some customer service issues over the years and a lot of people don't recommend them anymore. I have a Trifecta tune and haven't really had any issues with it, but I've decided I want to get more out of my car so I'm switching over to a tune from Bad News Racing. Jerry at BNR actually tunes to your specific car and your requests rather than just a canned tune that everyone gets. Not saying Trifecta is bad necessarily, but the BNR tune is worth looking in to! As for the air intake, in all honesty they do nothing for performance on these cars. They do get you some cool turbo noises so if that's what you're looking for then by all means get yourself an intake. If you're looking for horspower or MPG gains, save your money.
