Install the wideband and report your AFR when you're cruising. Otherwise it's just a guessing game.

Just filled up one of my DD cars and here's some great FD mileage. This is unusual for a stock car with stock ecu but the mileage on the car is really low and the compression is killer. Has a wrapped M2 dp and HKS hi power catback otherwise bone stock.

323 miles and 17.3 gallons of gas to fill which equals 18.67 miles per gallon

Miles are split between town, rural HWY (stop and go HWY style) and little back road fun.

A number of years ago, I sold a pair of 550cc primaries which averaged 24-25 mpg on 93 octane. They got me from Daytona Beach, FL to Macon, GA @ 70 mph (no stops).

A good tune will do wonders.

I take my car out to hit up canyon roads which I don't drive for economy. I basically run the car pretty hard in the mountains, and cruise there and back.

I average 17-19MPG with a single turbo on these drives.

i ussualy have a heavy foot. but these last 2 full tanks it was just regular cruising with soft acceleration and transtions and spending way to much gas that way. havent had time to have the wideband installed yet.

WOW!!!!

That's impressive.

The best I've ever gotten is the above unless it was straight hwg and then I might get about 22

I drove up to PFS, got 22.24 mpg going up, and 22.26 mpg coming back. This was on interstate at 75 mph, never boosting, taking it easy. Tuning is everything.

I checked mine as I'm using the FD daily ATM. And was well surprised to see I used 2 gallons almost exactly for 60 mile commute :O about 50 of which are motorway miles. That's 30 MPG :O

Did 60mph all the way on the motorway but did have a little fun off the motorway.

That's PFC running low boost on stock twins with FMIC and massive exhaust, in need of mapping. Surely only better things to come after mapping?

As it stands I should get easy over 300 miles out of a tank maybe 350 ish

Not that I'm particularly bothered about economy but it is nice suprise while its being used as a daily
