Modded G's what's your GAS MILEAGE ON A FULL TANK?
 

Ok I got Stillen TD exhaust, Stillen headers, Stillen test pipes, injen cold air intake, Plenum spacer and I get 220 miles a tank. Does this seem wrong? I finally calculated my mileage after I filled up my tank and resetted. What's your guys mileage? And please don't answer if your car is stock. Modded G's input only!!

I have an FI exhaust, 5/16 spacer, MREV2, Z-tube and Amsoil filter. On my current tank I just went below 1/4 and I'm at 322 miles, so I should get over 400. This is with regular 87 gas. I notice that with 91 or higher gas I get worse milage for some strange reason. I also do 90% highway driving so that helps.

UMMM WOW? You actually put 87? I thought it was real bad for our engine

My car runs the same with 87 as it does with 91 and like I said before I actually get better gas milage with 87 for some reason. I'll be getting a custom tune soon, so I imagine once I do that I'll have to run 91 all the time, but right now that's not the case.

I get ~230-250 on a tank with 538whp on my pump gas tune.

Only the rev up engines (05+ 6mt) NEED premium gas. Prior to 05 you can put 87 in, but 91 or high is suggested.

I just have a K&N and a Z tube and I get about 510kms to a tank, to lazy to convert to miles but if you care there you go!

I drive with a pretty heavy foot since I like to hear it roar haha.

Oh and me and TTrank are probably lighter than you coupes haha.

i have Mrev2, 5/16 spacers z-tube and pop chargers, and some 20" heavy wheels, and 130LBS worth of subs in the trunk. with 70% city, and 30% highway i usually get about 20MPG and i fill up as soon as the gas light goes on and thats usually at 335 Miles.

Just filled up this morning and got better than normal, I got 268 on the last tank and I was pretty hard on it.

i have a Greddy Exhaust, injen intake, and 5/16 spacer
i get about 250 miles to a tank....
