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!

HOLES IN 6 MONTHS. Huge disappointment, what happened to Saucony??
Size: 2.5 Big Kid, Color: Pink/Navy, Size: 2.5 Big Kid, Color: Pink/Navy
What has happened to Saucony kids shoes?? I've been purchasing this brand for all my kids' shoes since they were toddlers, my oldest is now 10.5 and she's had this pair for six months and they have huge holes in both the uppers. My kid hasn't even fully grown INTO this size, forget about growing out! I really expect more from this brand, I thought it was worth the extra cost you pay versus no name brands on Amazon. What a disappointment.

Cute and practical
Got these for my 8 year old for the school year. They fit as expected with good traction on the bottom. She's had them about a month and they are still holding up well. She loves them because they look cute and I love them because they keep her supported all day long!
