I would like to know how is the gas mileage after installing the spacer. Thinking of installing one. TIA.

i have a spacer for sale from AAM. i installed it once but, the car had to retuned because it would not stay idled. i figured since i have a single turbo that little extra power wasn't worth driving to have it retuned so i'm selling mine. it is supposed to make good gains though.
