I got the FRPP CAI with tune through the dealership since its a brandnew car and I didnt want to void the warranty. I am happy with the difference. I have been told I would be even happier with a brenspeed or bama tune. My question is .. If I purchased one of these ( I have the visited the sites and they do make them for the FRPP CAI) can I put in their tune and then when I bring it in for service flash it back to the regular before hand w/o them knowing or do they have the ability to tell otherwise?

Thanks
