I'm getting about 250-260 stock

I'm only getting about 225 miles (mixed driving) on 10-11 gallons of premium gas. My NX is 100% stock. It pulls left and may have other contributing issues.

My last NX would get 275+ easy (mixed driving). It had 2.5'' exhaust and a Perrin cone filter. The most miles I ever got on a tank in that NX was 375, and I still had about 1/16 of the tank left. That was all highway and driving 85-100MPH most of the time. Not sure how that happened. That car loved highway driving.

I got 350 highway miles DET/28r 3" turbo back!! usually just get 350 though

I usually get around 320mi

the two cars from my sig:

- Grey NX: ~230 miles/tank, 9 gallon fill-up = 25.5 mpg

- Red NX: ~280 miles/tank, 9 gallon fill-up = 31.1 mpg

this is averaging the same kind of driving each, some long distance, some stop-and-go. ran the tank to less than 1/16 tank (on the gauge) each fill up. filled to the same level every time.

Stock motor with T28 kit with 370's - I usually get around 220-260 to a take and average around 24mpg. Wish it were higher, lol

how do u guys get such good mpgs?

maybe modded ecus.

I've heard that the "OEM" setup is waaaaaaay to rich.

I even tried tuning my Calum Basic ecu to idle and cruise a little leaner than normal, and still cannot get past 26mpg ever... who knows?
