Very funny. Not married, so no permission slip is needed. I drive 90% interstate to and from work, 75-80 mph, averaging 25 mpg, on a 100 mile round trip commute. Would dropping a $500 - $750 CAI and exhaust really be jusitifed? Sure I'd blow it out from time to time, but I'm not a racer and I don't see myself doing much more to the car as far as performance mods. Looking for better gas mileage and better growl.

you want better gas mileage, drive 69 mph instead of 75 and 80. . .

i get 26.5 to 27.5 at that speed. . . trust me on that one

Only 1 to 3 based on you driving the same.

Mine went down from 14 (tune only) to 13 (tune + CAI) but that's because I'm "on it" a lot and do next to no hwy driving. Trust me, you will be "on it" too.

Got an 06 GT, purely stock. Thinking of a CAI and axel or CAT back exhaust. I know I need to reflash the engine, but my question is, what miles per gallon increase would I expect to see if any. Bear in mind that my driving habits will remain the same.

I would think from a theoretical standpoint in order to increase gas millage you need to either load a computer program designed for that purpose or get rid of some of your stock items that are turning power into heat. A CAI+tune will only give you the opportunity to burn more fuel when you put your foot all the way down, I dont think it would make anything more efficient. I would think that pulleys, headers and an off road Xpipe would be the things that are going to turn less horsepower into heat.

I have a CAI+tune and now I get worse gas millage (from 18 to 17) and I am running 93 octane all the time because I like the extra power. So now I am spending about the same $ per mile as my old durango! Maybe its time to get a GSX-R750 just to do my part for saving the environment... yeah, thats the ticket...
