Gas mileage
Okay, my car has had these mods: K&N CAI, LS6 intake, Pacesetter long tubes, GMMG catback, !EGR, !AIR, and just recently found out I have 3.73 gears. After using 3/4 tank of gas, I'm sitting about anywhere from 120 miles, and sometimes 160 miles. Right now I'm at like 165 sitting halfway between empty and 1/4. Last time I filled up, I only got 135. I did spark plugs a few months back, checked my tire pressure, also sea foamed my car a few months back. I'm about to change my fuel filter, since I haven't done that since I got the car(about 3 years now). Would that regulate my gas mileage more? Or what could be the cause that sometimes I get low mileage and sometimes a bit higher?
Also, a more important question, with my mods, is that just my average gas mileage now?

Pretty sure it's working. When it's near E and my car starts to not want to go no more... pretty sure it's on E. =p But I changed out the fuel filter, so I'll check again after this gas tank.

hmmm, something aint right. im getting better mileage then you and i drive my car hard. next time fill your tank all the way up. drive around until it close to empty, fill up until the gas nozzle shuts off and divide that number(# of gallons) into how many miles you've driven. that should be more accurate then saying im getting 160 miles with it being between empty and 1/4 full or w/e

And remember the fuel pump is cooled and lubed by the fuel, I never let my tank get too low before refueling. Running out of gas really shortens the life of these things.
