On a log manifold with my f22 motor, i made absolutely no power compared to my full ap2 setup, and lost 2-3mpg on the highway.

 

lost mpg because of a lack of retune im guessing? or you lost that amount after a retune?

 

Car was initially tuned with ap2 setup, then re-tuned after the AP1 cam was installed, including a road tune. After reinstalling the ap2 intake cam I gained 2-3mpg, or regained it depending on how you look at it. For my log setup with 3mm headgasket, i gained no power and lost MPG.
