my car is pretty much stock except for i run full synthetic and have a high flow k&n drop in filter i was wonder what kind of mileage everyone else was getting to a tank? im get between 300 and 325 a tank depending on if i get on it alot
 


Is yours an N/A or S/C Mikey? Mine's an N/A but for some reason my mileage hasn't been all that great lately.
 
i get right around 350-370, I'm slightly modded and most of my miles are highway. I've got CAI, ZZP PCM, smaller pulley, and 3" exhaust from downpipe back.
 
I haven't maxed my car out since I've got this done. Haven't had the time to find a road straight enough to try it on. I've hit 135 a couple times though.

Is yours SC? If not I think I'm gonna be getting my PCM soon too.
 


I get 18-19MPG in about 60% HWY driving!!! Thats running 87 octane, if I put in 89 with the 10% ethenol, I dip into the 17s!!! On a road trip, I've never seen it get much past 24!!!
 
i have a bone stock comp g and i got 25.6 @ 88mph on the interstate and usually 18-20 average on e10. i average 16-18 on e30.
 


04 comp G__ fill tank 87 octane mixed highway and city i have to refill between 290- 310 miles ifs no excessive speeding or fast starts from stop looking to try and get 350 miles per tank maybe a cone air intake filter will help
