EJ20T Modded MPG thread

ok ok ok, I know there are a lot of these threads out there with older results, so I'd like ot see what everyone else is getting from the modded EJ20 and list what mods you have as well as what kind of driving.

I've been getting about 18 mpg lately and have a protuned stage 2 map (up-pipe, down-pipe, CBE, IC y-pipe) and its a 4EAT so I know that lowers me a few mpg

oh, and my commute is a little more "tiwsty" than most peoples probably so I know that drags down my mpg too

I got 23 mpg mostly free way cruising at 75ish MPH with some WOT passes one half and slower 65-70 MPH (also colder weather) the other half

thats what I thought, but mine didn't seem to make too much of a difference. Once I get the manual swap I'll get the tune tweaked

Currently weekend warrior, but even when it was a daily driver I rarely got more than 235 per tank. I blame my right foot.

There are places to get 93 and 100 in ca, although it's not readily accessable. I don't think I've ever gotten better than 20 mpg.

I just got a boost gauge put in yesterday (Speed Element shout out!). Now I see why I only get 15mpg

... oh, and I was able to enjoy it just long enough for some **** to find out how far she could fit her Civic into my rear bumper.

Full coverage insurance FTW!!!

Wow that's pretty decent!

I was running stock turbo on my 03 WRX wagon with lightened fly, (standard edition) RA gears, uppipe, TBE, among a few other engine mods, without a tune, and I could get 350 on a tank before the gas light came on. With it tuned I think I got about the same.
