Daily driving in the city/freeway, I'm only getting about 20-21 mpg since my stage IV was installed. What kind of mileage do you guys get?

depends how you drive and how well tuned you are.on a come day i pretty much have stock mileage.hard driving bout 18-20.hell when i was tuned real rich i spent a whole tank of gas in a 3hr trip(and this was on the freeway).

haha I ate up quarter tank of gas racing down a mountain. Well my mileage has always been the same 300 to the tank. our MPG is suppose to be 22 MPG your not too far off.

It is all in the tuning of the fuel system. No comment on my gas mileage with my crappy tuned setup. :( Maybe I will have more to say about my new setup this summer. ;)

I'm just trying to keep my car running, lol. But i've only put about 50 miles on mine since the dfi and fuel setup install.

a full tank of premium/turbo blue blend lasts me 200 miles. That is normal driving with on average a few good 20+psi runs... When I really get on it, tank lasts about 150miles... I know, I know, that sucks, right? Well, your not the one behind the wheel with high boost at your finger tips, you'd be throwing down the hammer too! :-)

i remember when I had a new motor in I went 500 (barely) on a tank of gas..with the turbo and ocanssional boost I get about 25 town and 31 freeway... Check your EGR to see if the valve moves when you rev it to 2k..if not then your diaphragm of your transducer (the flying saucer thingee) is shot. or clean your EGR valve itself.

my gas mileage sucks ass bigtime

I'm with you, Brad. It's very hard not to drop the hammer sometimes, and in my case, pretty often when traveling to and from work.
