wow thats old,
Anyways, the things I noticed gave me better mileage were the underdrive pulley, I switched to all royal purple lubes, K&N air filter. Actually the headers helped a little, but its now just too tempting to hit it hard. Oh yea, and I got better gas mileage when I pulled out the old bosch plugs, I didnt put them in there, but as soon as I noticed I pulled them out. I usually average about 22 mpg with my M6, that is mixed driving, freeway and surface streets about 60 miles a day. Also that isnt granny driving either, I get on it every once and a while. Especially when there are stangs or ricers around. Gotta remind them whos the boss, lol
that sounded gay
