17?!?!?!?My worst was 20 with my old cracked head. No compression meant it drank a lot of fuel.They way it is now with the aaz head, 2.5 inch straight exhaust - split to in front of rear tires, gov, lots of fuel, boost pin at MAX i was getting between 28-35 and i was driving it like i stole it.I'm thinking to reach 17 i need a bigger pump head!!! and a lift pump...both things that are currently on my agenda
