Wondering if the stage 1 tune gets better gas mileage than stock. If so what improvements have you guys seen?

Interested in an AP for a 2015 WRX.

TIA

I saw an improvement in fuel economy when going from stock to tuned.. probably mainly because I didn't have to press the gas as hard to go the same speed. If you drive your car harder after the tune, then I would expect fuel economy to decrease. It's all in how you use the pedal.

I saw absolutely no different from stock to stage 1. Drove stage 1 for like 4 months. But definitely saw a few MPGs decrease going to stage 2 recently.
