Mostly city driving with absolutely no other mods whatsoever.

I was getting 28/41mpg, then I found out I had a clogged fuel filter and needed a full fuel system flush. lol

Now I get 25/31 like I should.

on my irl stage 2 i could get up to 400 miles per tank. and she only held 12.5 gallon's. and i never went into reserve.. i kept out of boost but still pushed the rpms to like 3k just a tad under. **** my first tank i got alittle over 430 miles on the car before the refuel light came on. it's ALL about driving style. saw that kinda mileage on stage 2 since the first day it was out.(had the first 07 GMPP stage 2 IRL LSJ.)

I have had stage 2 since I bought it in 06, and we have a 27.6 mpg average (average speed of 29.3 mph) On long trips, like to FL from IL we get 38ish + ,the stage 2 car is better then the stock for MPG. (atleast mine was)
