I've read about it before but can't seem to find it through "search". Anyways, I'm about to go on a 600 mile trip with my 951 and was wondering how good/bad the fuel economy will be. These will be all highway miles, so those of you with modified 951's that have checked your mpg on the highway, please post your mpg and tank mileage. Thanks.

I get around 15-16mpg city driving, not even 300 miles on a full tank.

A little under 17 avg around town. I've gone up to about 320 miles on a tank before. On the highway I avg about 28-30mpg getting over 500 miles to the tank.

Never kept track it of it in town, get about 27 on the hwy if I keep it under 90.

wow, thats not bad...near 30 on highway. I just put the stock chip in my n/a to get better fuel mileage since that is no where near the "fast" car of my bunch. Haven't tested it yet. I've got msd ignition on the turbo and I have the emissions papers from before and after it's install. Big difference. I wonder if it'll help in mpg's. Guess I'll find out next week.

~30mpg on the highway depending on speed, traffic, and if I'm using a/c

The last couple of days I've made a lot (A LOT) of full throttle accelerations to try out the new MAP system och playing with different boost/fuel settings etc.
Half the tank went away in 180 km...

I have no thermostat.... I was busting out 10 or 11MPG on saturday, driving like an absolute maniac (along with over 20 other front engine owners ). Highway... Low teens. A half tank in just over 100 miles

Getting yet another tstat later this week. Im starting to think my cat might be plugged...

I did nearly 1 tank in one day when I first started tuning! Now I run it very lean on cruise... cant wait for water injection to put more timing in under WOT!

I really couldn't care in the slightest.
why does everyone make such a big deal about it.

you pay to play.

All I know is that when I go rallying I can go through half a tank in about 45 minutes

my gas mileage doesn't seem to be that bad when i used to drive it. I was runnning75# injectors but when i got on boost alot gas don't last long
