I'm just wondering how horribly the AFC hack decreases your gas mileage (out of boost)?

If tuned right it shouldn't. You probably will never know because you will always be in boost.

 

I used to get about 30 miles to a gallon before then when I got the afchack not beating on it I'd get like 25-27 untuned stock settings(~40 across the board).

 

My fuel economy has stayed the same with the hack.

My application is a bit different, but if you are still getting 14.5-15.0 AFRs on your wideband while cruising (as you should if you are still OBDII and have it tuned in the right ballpark) then your fuel economy shouldn't suffer.

Of course, my fuel economy goes to **** when I start going into boost often, but usually I am just driving sanely on the freeway.

 

I used to get 30+mpg with the hack. still sucked though

 

out of boost my mpg is pretty stock like


on boost i run rich like a ****

on the dyno i dipped into lower than 10's for a while, but i noticed the baseline ran between 11's and 13's

 

It seems like my car is getting terrible gas milage since i put 440s and the safc on but i think it is cause when ever I drive it we are out beating on it.
