Works as it should
Fits and works they should. Just be mindful, this product does NOT include mounting hardware! But otherwise a great product and price!

I3 Platinum
Initial use of the tuner is pretty easy. Watched a video on YouTube and spent a few minutes on Diablosport’s website and got after it! I drive a 2016 Silverado 1500 with the 5.3.
Picked up 1-1.5 mpg so far in 45 miles of driving!
I turned off AFM and that in itself made the truck more driveable! Looking forward to towing my 7500 lb camper!
