Wow, so many choices my head is spinning. The more I research the more confused I get.

 

Same here

 

I have the ETS installed. No complaints since I have had installed on the stock tune. I recently put on the Cobb AP stage 1 for the SF intake. There is a great performance increase! The logs all looked great except I had one with a high amount of knock. If you are going with a custom tune with the ETS you won't regret it. Its a high quality intake.

Just to be safe for me since I don't want to pay for a pro tune at this time I am going to purchase the Cobb SF and Cobb inlet pipe.

Talking to Cobb tuners they say there isn't really much difference between the gains of an intake after a tune if your on the stock turbo anyway. They say the bigger gains come from the test pipe and exhaust when going to stage 2.

 

The biggest gains for me came from the test pipe and the intake (and the custom tune obviously.) The exhaust didn't make that much of a difference.

If one was looking to get the best bang for the buck, I'd go with an intake, a test pipe, and a custom tune and call it a day. But the power is addicting so lets face it, nobody stops there.

 

I think I am going to go with the ETS for sure. The AMS came out to be a lot more than I thought once you added the bungs and the flat black color. Probably order it this week. I looked at the Cobb but was told to get a tune from the shop. I do like the idea of the Cobb, especially being able to flash back to stock. I am going to talk to the guy I plan on having do my tune to see if that is something he can do as well. Plus I don't think the Cobb works on the 2012 yet.
