The EDGE Insight+ CTS3 Monitor & Custom Tuning Device for the 2020-2023 GM 6.6L Duramax L5P is the ultimate performance and monitoring solution for your truck, delivering all the functionality of the industry leading Insight CTS3 with the added capability of custom tuning.

This kit is built specific for 2017-2019 GM L5P Duramax applications and includes all required hardware to be able to monitor and unlock/flash ECM/TCM third party calibrations into the truck. Kit includes our revolutionary Locksmith unlock tool, ECM unlock harness, and our cast A-pillar mount for an OEM like fit of the Insight+ monitor in the cab. Whether you’re looking to keep a close eye on vital engine parameters or load custom tunes for optimal power and efficiency, the Insight-Plus has you covered. Pre-loaded with a custom tune license, this device allows you to read your truck’s ECM/TCM and create a backup file that can be sent to your preferred Edge approved custom calibration shop. Once your tuner customizes the files for your truck, you can easily upload them via your PC and flash them to your vehicle in just a few simple steps, this tuner is built to grow with your needs.

Beyond tuning, the Insight+ provides real-time monitoring of key vehicle parameters like EGT, regen cycles, transmission temperature, boost, RPM, and more, all displayed on a crisp, easy-to-navigate touchscreen. Swipe between customizable layouts for towing, performance, and economy, or take advantage of built-in performance meters to track 0-60 and quarter-mile times. An advanced data logger lets you export driving data, while integrated diagnostics allow you to read and clear DTC codes with ease. Installation is simple, just plug it into the OBDII port, no wiring required. The Insight+ also features Wi-Fi updateability, manual and mobile DPF regeneration capabilities for select diesel applications, and compatibility with Edge’s EAS (Expandable Accessory System) for adding sensors to monitor even more parameters. For those who like to keep things clean and factory looking cabins, it can also control 12V accessories like auxiliary lighting directly through the touchscreen, eliminating the need for extra switches cluttering your dash.

Sleek, powerful, and packed with features, the EDGE Insight+ CTS3 is more than just a digital gauge, it’s your key to unlocking your truck’s full potential while keeping it running safe and strong. Whether you're a daily driver, a heavy hauler, or an enthusiast pushing the limits, this is the performance tool you’ve been waiting for.

This shirt checked all the boxes, comfort, fit and feel.
Size: 3X-Large, Color: Teal 02, Size: 3X-Large, Color: Teal 02
OMG! what a nice shirt. The pattern is awesome and the material is very soft and light weight. It is so breathable. Material has a bit of stretch so it very comfortable sitting or standing and does not wrinkle. I will be ordering at least on more in another color

Surprisingly awesome. Seriously. And I hate buying clothes.
Size: X-Large, Color: Black
I'm 6'1", 215 with large shoulders and chest. "Athletic dad-bod." Nothing fits me perfectly. I'm constantly stuck between an XL and XXL shirt, and a 37x31 pant---so literally nothing fits me and if you're a big guy, we all know that most polo shirts look like crap and fit like garbage bags. The shiny tone first made me skeptical. I wasn't even going to take it out of the package. But for $19, I said screw it. It fits really well. Not slim fit, but not "Ralph Lauren trash bag regular fit." It's soft like textured silk. It looks good and is the perfect length if you're 6'-6'3. And no--I know your first thought with the texture and shine is "does it look like a cheesy club shirt on a NJ Italian guy?" Shockingly, no...it's actually really nice (yeah--I had the same thought). It's stretchy. It's relatively form fitting, and it's cool to the touch. I immediately bought 3 more. For $19--just buy it. You won't regret it.

Good shirt
Size: Medium, Color: Teal 02
Love the color and the design of the shirt. The small threads it’s made out of starting to come loose though. Now when look down at chest and stomach area, there are 15+ little strings that pop out of the shirt.

Awesome shirt!
Size: Medium, Color: Blue, Size: Medium, Color: Blue
This is a nice shirt! Let me start by saying I am 6 foot 2, 195pounds with about a 40 inch chest, 42 inches on a good day! Ha ha. I ordered a medium because I wanted an athletic fit. The medium fits just right. For those wanting a normal, roomier fit I would recommend the large for my size. I’ll get a lot of compliments when I wear this shirt. What I like about it is that it is wrinkle free and looks great, I would not wear it on a super hot day with a snug fit. I do live in Florida, so that makes a difference. I also ordered the black one, both the blue and the black look very good for dress /casual. It’s polyester so it’s not super soft, which is OK. That also means it does not shrink.
