For those of you that have the turbo setup. How much did your mpg change from stock while running your turbo ?

 

after the second month....not much.

 

I get better highway mileage (~31mpg) and approximately the same city mileage depending on how I drive (18-24mpg).

 

Wow thats awesome =] Thats good to hear.

 

yea i get about 20average mpg city. a little less and a little more depending on how many red lights frustrate me! =P

 

I get better mileage in the city, and amazing highway. I attribute this to the car making more power in the midrange, thus not needing to use the throttle as much.

 

hey spec ops, how did you manage to get a high mpg. Does having a wideband connected to the aem ems and running a close loop help that a bit. With my set up with only making 320whp i may be averaging 24-25 highway and and about 19 or so city. My afr at wot is 11.02 and seems to be under 14 anything above 3000rpm.

 

I have O2 sensor feedback enabled on my EMS and have it set to ~13.8 when under 5k rpms and 0psi (aka only works in vacuum and under 5k rpms).

Other then that, its just my overall tune I guess

 

wouldnt the gas mileage all depend on the size of ur injectors, how much boost ur running and and how often u hit turbo

 

pretty much, but that all only affects gas mileage while in boost. Out of boost its the tune since the engine should not be using any more fuel then stock.
