This was the First GM CAI to be done by the dealership, so my Camaro was their very first. The install and Tune were done without any problems or issues. So far the car's system is relearning, and I have been informed to make a good road trip with the car as soon as I can, which I will be doing this weekend when I drive up to my son's place in Murrieta, CA.

crazy, did it myself in 20min and just had the dealer flash the tune. Its a bolt on, easy install.

I decided to have the dealership do the install because New owners had just purchased said dealership. I had a very good relationship with the prior owners and I wanted to maintain that with the new owners. So I had them do the whole job, this way there can be NO one saying that I messed up something on the install of the CAI.

Here are the changes in the factory SS tune and the tune provided by GM for their CAI.

First Stock:


GMPP CAI:



I have the MAF calibration changes saved to an excel, but don't know how to post tables here and also considering this impacts emissions it may not be a good thing to share.

What I can relay is that almost every single cell of the calibration table is changed by a decent amount. The charts may not show it clearly, but GM is expecting this intake to flow more at all Hz values. The axis values are also changed with the CAI having higher axis values.

How that translates to power is up to the dyno and track results, but I now understand why Tim at EFI has been so on board with rotofab and not skewing MAF tables.

so youre saying rotofab is a better choice
