Currently showing 25.0-25.2mpg

Mostly city driving with absolutely no other mods whatsoever.

So, what are other "virgin" GMPP Stage 2's getting?

I got 31.3 I believe on a 60 min trip....now I only get around 25 like u

i have gm stage 2 but with zzp pcm, and i have a intake i get 24.7

I've had the GMS2 on my car since May '08 and and I've been getting a combined mpg of 28-29!!!! On the highway I average 32-34mpg's. Gotta love it!!

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. :)

Im not sure in the city (theres A LOT) of hills where i live so it eats up gas, but highway, i get 36mpg almost all the time. :twothumbs

did you just install it? Ive seen many get 35mpg.

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. shit 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'm seein 22.2 as o today,that's drivin 70+ on hiway,boostin a qute a few times an runnin anything that wants to run, before I changed plugs, cleaned air filter an inflated tires I was seein about 18 average I'm stil on st. 2 tune

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)

update: 31.1-31.3 MPG half city half highway. :D

Yeah rallyracer says over time his mileage has increased with the stage kit...so just give it some time ;)
