So, today I filled up and to my suprise I got 325 miles out of this tank . Sad part is I probably could have squeezed another 20 miles out of it. I was so happy because usually I get only about 275 -280 on a fill up. What kind of gas mileage are you guys seeing. Keep in mind I ran a f150 lightning 3 times and a cobra 2 times on this tank, so I wasn't babying it. One of these days I will try and drive a whole tank without going into boost and see what I can pull out of it

 

I'm right there with you at about 320
I am never very easy on the car and I still get around that mpg.
I have tried to go a whole tank without boosting but for some reason that never really happens.

 

i went to p-cola for 2 weeks for more training all highway miles i got 430 miles on the way there... i kept it under 2800rpm but on the way back i was doin 90+ just to get home an only got 330

 

damn, 430????????

 

yuppers... i was like whoa!... seems u get way better gas mileage when u keep it under 2800rpm... my guess is below boost?

 

damn i cant seem to get 300, but im all city. are you guys city/hwy for the week or is it just my heavy foot. but i usually granny shift around 3g

 

on my sti stage 2 im averaging 235 miles per fill up but it always stops at 12 gallons. so i have 4.9 left. so about 19.5mpg.

 

I have mine in stage 2 all the time and I average 325 per tank. I have squeezed out a couple 355 tanks before.

 

Not quite sure about the tank milage, I usually fill up around 300 miles. I average 23-26 mpg.

 

Damn, I thought my 320 was a lot but I guess that is average. I have killed a tank in like 180 miles before though when tuning.
