The thing is, My gas mileage is great with 22-23 mpg. I rev 3100 in the 65-68 range with the two speed and what I believe are 3.23 gears. I've been told that my rpm's sound too high for them to be 3.23's. People always say it sounds more like 3.73's.
Anyway, what kind of gas mileage increase can I expect from adding the headers intake and carb. I'd like to see 25, is this outrageous??
