Simple to update and use, canned tunes are good, but... I cannot adjust tire size on my 2017 Yukon Denali as it conflicts with the adaptive cruise -one of the primary reasons I chose it. I could have gotten just the decent canned tunes/afm disable/throttle progressivity for far cheaper than I spent on this. Tech support hasn't responded to my emails, but it's the holidays. I'll update this if I resolve the issue.

The fact that I have to have a computer is rediculous. Could care less about the 40$ to unlock. I don't have access to a computer so I have a 500$ bookmark now.

Install of the computer program and download was weird to say the least. For 2017 and up Chevy it asks you to pay more. I started to pay with PayPal, backed out, then it said I unlocked the GM code to device?? I tried it and it worked.So did the computer download stuff make any sense? NoDid the install to the truck go smoothly? YesDid it make a difference in the truck attitude? Most certainly. I lost 1mpg (probably because my foot is in it more. I added a Borla Exhaust (not duals) and a AFE dry performance air filter. The truck sounds great and runs great.My tune:87 octane. Increase the pedal response +6. Disable AFM, adjust tire size for speedometer. That’s it. The truck really does run better and smoother through the gears. More pep, less hesitation, and less unnecessary shifting.I knocked a star off for the weird pre install stuff, but the product itself worked.*if you try to skip the download to your computer and go straight to programming your truck, it will not work. It says Download required or something. Try purchasing the $40 download then back out and see if it unlocks the code for you too. If not, it’s truly worth the extra $40 anyway.

Works fantastic on my 2018 Silverado 4x4 5.3 litre. Gained a couple mpg. Able to deactivate AFM. Always runs on 8 cylinders & still gets better fuel economy. Very programmable.

2017 silverado 5.3 with 6 speed trans. this superchip 2874 has worked out well. Plugged it in to computer and downloaded agreements off of superchips site then plugged it into the truck for the tune. Had to take truck in for recall just put it back to stock before going in, then tuned it after no problem. Plus that it will read check engine codes if needed.

Works great and able to change settings from towing to 87 octane to performance. Performance mode is a big difference. Different Truck now.

Excellent. Bought for my 2017 GMC Sierra.All I needed to do was change tire sizes and disable auto 4 cylinder options. Plenty of programming options to play with should I change any performance upgrades in the future. Had to update the Flashpaq from the PC on first use, took some time but worked out at the end. After the update, I tought you had to pay an additional $40 to use the product, but that was only an option. You should only need to pay to use the programmer for additional vehicles. Easy to use and highly recommended.
