i mean im granny shiftin 1-3-5 keeping it under 2k each time and the pedal never hits the floorboard, i could only imagine if i put my foot into it!! The car runs fine, but for some reason, i think its burning to much fuel and my afr on the tune was around 13.1 flat all the way through to redline.

same here, my my mods in sig i get around 27-29 highway but in the city i dont get crap cause I cant keep my foot out of it. With a tank of gas i usually get around 200 miles or a lil more out of a tank. deal is i dont drive what I drive cause I care about gas mileage. i just picked me up a toyota truck for that.

when i had my '96Z28 i had LT's, ORY, Magnaflow mufflers, 3.73's, 6 speed, MadZ28 tune and some other stuff and i got 27-29 mpg highway and with some spirited driving thrown in around town i got about 15-18 mpg. I didn't care though, as i too, love to listen to the pipes

I just wanted to clarify something, I don't care about the gas mileage because gas is high, i care because it seems like something is wrong with the car if i can't get better mileage. That means ill be in single digits with any spirited driving and some of you guys have a cam.

I think the problem is you are skip shifting... are you bogging it when you skip shift? I run through the gears like normal, highway and city... the number i gave was an average... if i did strictly city i'd probably be at 17-18.

not really bogging the car. When i say city, i mean a stop sign every 30ft and a light ever 100ft. I shift into third at around 2k and the car will bog if i floor it, but i accel slowly since i have to stop again because of lights and stop signs.

What are your rear gears? But yeah stop and go like that will kill it... Also have you tried changing plugs and regular maintainence items recently?
