Interesting. My understanding was that the MP215 (or any AP3) purchase included custom tuning revisions for 45 days. If I'm wrong then out makes it seem like a pretty horrible deal considering the additional $150 charge for custom tuning and the $580 premium over the Cobb Stage 1 package.
I have the MP215 kit sitting in my garage. The kit needs to be installed at a dealership to register the warranty with Ford Racing. If I could go back in time, I would buy an AP from Mountune then wait for the right induction kit, intercooler, Dp and cat-back system then tell them I want the custom tune for my specific setup. I would then have 45 days to data log and for them to tweak my tune from the day they first sent my tune.
