Thank you. Do you have a schedule for doing tunes at your facility in Idaho?

@BlackBearPerf I have a 2015 Yukon XL SLT and am considering tuning it based on the previous posts. A few questions, do your tunes cancel the active fuel management? Also, does gas mileage tend to be affected positive or negatively and if so, how much? Any other tips or thoughts on why to tune it? Thanks!

We would be happy to help. We can disable the AFM within the tune, although AFM is typically a fuel saver on the 2014+ models, so we would only suggest disabling it if you have heavy wheels/tires or can't tolerate the sound with your exhaust.

We strive to unlock every bit of available power from your engine. This typically results in a 25-30hp, 30-35ft-lbs and on average 1mpg improvement along with improved shift patterns and throttle response, all depending on fuel quality, octane and vehicle condition prior to the tune.
