-Thanks

Never had a JWT ECU that caused low gas mileage.

Go change your O2 sensor.

or

check and see if any of your Inj O rings are leaking a bit.

They only change they make to the fueling with that program is at WOT, and they lean it out there. Its something else.

Data to support Andreas Miko & Calum - for my 93 se-r:
73,161 miles before JWT ECU & S4 cams = 28.28 mpg
65,623 miles with JWT ECU, S4 cams, 15x lb weight reduction = 32.97 mpg
I'd guess about 60% of those miles are city driving.

Is your tune setup similarly? My highway gas mileage has been so-so. Granted It's hard to stay off boost .

City has been about 21mpg, which is fairly good considering the fact that my NA got 21 on average too.

No, you don't lean a turbo car out at WOT.

Ooops not exactly what I meant, I was aiming towards if your tune is similar to JWT tune for the same setups

What care are you talking about? Don't tell me you put a N/A motor back in your car haha

I was doing about 35mpg with JDM 10:1 DE, Calum ECU, HS CAI. N14 chassis.

its my buddy that just bought a b13. i thought about going back to n/a i need a daily for school lol but im back up and running had it down for about 2 weeks
