Not to mention my compression being 11.25:1 versus his 9:1.

His car is not suffering in the MPG, because of his gears.
Got it.

10:1. ;D GT40P heads. Also my car is most likely heavier since I have quite the sound system and other technologies. Also, my car isn't Mass air.

Speed density with a cam is my guess. There are few came that work good with the factory speed density due to a lack of vacuum at idle. The cars can run great one min and be pig rich the next. Just my $.02.
