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!

Better jeans than I expected
Size: 29W x 34L, Color: Rinse, Size: 29W x 34L, Color: Rinse
I pretty much only wear Levi's 510s & as of lately Asos skinny jeans. Thought I'd give these a shot. I wear between 28w-30w so I ordered 29w. They fit good & seems to be really true to size. I could have probably ordered the 28w for a tighter fit. Only reason I didn't give them 5 stars is that the dye transfers from the denim. I'm sure eventually that will stop happening?? I like the dark denim so I don't wanna continue to wash them so they fade out so soon.

Great jeans. Sized write
Size: 32W x 29L, Color: Rinsed
Great jeans for the money. I would say they are as good as Levis. They are sized write and have more waist and inseem sizes. I have 10 pairs probably.

Depends on how it fits you I guess
Size: 33W x 29L, Color: Rinsed
They're okay, but don't really fit me well for some reason. Loose in the hips, tight in the crotch, they're supposedly my size based on other jeans. Back pocket of all stretch styles is too loose; wallet falls out too easily.
