The 2020-2023 6.6L L8T powered GM gas trucks have been locked down since their introduction. Owners of these trucks have been waiting patiently for a tuning solution, and DiabloSport has delivered in a big way! The new 9266-R kit includes our industry leading Trinity 2 on-dash tuner, along with the locksmith device and harness required to unlock both the ECM in your truck. Once unlocked, the Trinity 2 offers up tunes for 87, 91 and 93 octane fuels, as well as 2 transmission tunes to choose from. Beyond the preloaded tunes, we offer a host of user adjustable parameters, like throttle response, speed limit, tire size, and of course, DFM disable! We've even added some new features for drivers of these newer trucks, like the ability to recall your last mode setting, or to retain your auto-start-stop setting. Of course it doesn't stop there with T2. The full color, 5" touch screen allows you to keep an eye on all your vital engine data. The on-screen gauges deliver all the info you want to see, in real time. Of course, it can also record data for playback on our DV2 software for further analyzation. T2 also allows you to set up virtual alerts, and supports our Expandable Accessory System (EAS) for adding and logging additional external sensors. The device is internet updateable, either through our Update Agent software, or through its built in WiFi. Get power you can feel, with DiabloSport!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.
