Does anyone have any idea what it gets when its stock and what I am to expect with these mods. Was gettin just under 200 on a full tank. Just changed the plugs a lil bit ago and did see an good increase. Does anyone think maybe a fuel filter change might help. I bought the car used with about 62,000 on it and i doubt it has been changed.
I've got a 94 GSR which I bought in 98 with 63,000 miles. Totally stock engine and tire size, @ 122,000 miles now. I get 300 miles/tank if I keep my right foot light. 150-200 miles if I am always jammin.
