Fuel Millage Problem

so i just changed the plugs out to the new e3 diamond fire plugs. heard really good things about these. also i got a drop in k&n air filter and did the deck plate mod. just went and filled up so we will see this week how she fairs now and if this helps at all.

i noted my plugs were a little on the black side and they smelled a lot like gas so i know im running a bit rich. but they were like that before when i have my catalytic problems so we will see.

 

4:56 gears and oem spark plugs, when was the last time you changed the air filter?

 

no, im running 4:30 gears and i just mentioned the new plugs. unless your telling me thats what i should have. i dont plan on re gearing anytime soon. and i just put a brand new k&n filter in as to what my previous post says

 

One error in calculating the MPG is caused by the speedometer not providing the correct distance because it still thinks it's on 30" tires instead of 33" tires. A 33" tire goes 10% farther per revolution than the 30" tires. That alone would add 10% to his MPG calcs.
