If you keep your foot off the floor, you may see an increase. lol You'll have to test though as many factors can affect mpg.

live in a small town and dont often travel over 40. im gettin around 18 mpg.

the way i figured it is if the SC is in a vacuum till i mash on it, and the CAI helps with effeicicy a little bit. i might see an increase at normal driving like i do.

guess my thoughts werent too crazy lol

No, your guess wasn't crazy at all. Open up any restrictive intake and you could see a couple mpg more. Same with exhaust.

i havent looked into exhaust for the car yet. figured it would be really expensive and almost not worth it.

Look for a possible LOSS in city driving, but a gain on the freeway. This is based on the response of my two L67'* and their mods.

I'm no engineer to say the least, but let me say this (and give the great BC it'* deserved props...) before I really joined the BC I was literally getting at best... about 12-14 MPG. Now, after a few mods (CAI intake, 180 stat, Autolite Pro wires and NGK plugs) I'm seeing about 18-20 MPG. I plan on making a few more adjustments, and I'll let you know how it goes. Keep in mind I am an older NA, not later model SC.

Good luck!

DRIVING STYLE. Some people use the power differently than others. In normal 'controlled' driving conditions, City mileage will drop off, freeway driving will increase mileage with mods.
