2013 6.2 Sierra SLT Tune
My truck is stock except for a cat-back exhaust and an air filter. I noticed in the past few years that my mileage has dropped and no matter what I do the mileage doesn’t change. All Fluides plugs wires, O2 sensors all had no effect. I have had the truck since new, this is the first time that I have seen a difference in mileage and power. I can really feel it after 4500, now she really pulls on the Hwy.

Great product
Fixed the one major issue i had with my truck...the lagging throttle pedal. Since i bought the truck i never liked how much pedal travel you had to apply to get going...this sharpened it right up. the first time i drove it I was like WOW ITS FIXED. Updating the software was super easy and only took a few minutes on my desktop. Would highly recommend. Performance was a mild increase but my truck is stock so far.
