Instantly noticeable increase in power without a trailer.
Much easier pulling of 7500 lbs of trailer, horses, and gear, and a 2.4 mpg increase over 50 miles.
I’ve found the highest setting works best all around in my ’23 Sierra Denali.

I have not had good luck with mine. I have a 2023 GMC Denali and I did notice the power increase immediately after install, but my check engine light came on the next day and it threw a bunch of codes after only a day of driving it. I sent it back to make sure there was nothing wrong with the module and then got it back after AG tested it and it worked for about 5 days before it started throwing codes again. When it throws codes my truck performance is very poor and it also messes with all my electronics. When it works it works great, but unfortunately mine didn’t stay working. Customer service team at AG is great!

I initially installed the harness without the module plugged in, within a few days codes popped up, I contacted tech support and as per their recommendation returned all items for inspection. Within days I rec’d the module back with updates, and a beefed up wiring harness. The entire unit has been operational with exceptional results. My combination city/overall mileage per tank has been 30+ at 700 mile fills, prior to installation mileage was average 28.4 per fill. The power increase is quickly noticed, and very notable. My unit is on the high power mode.

First off, I do want to say the customer service has been phenomenal! I was given this product 100% for free which was beyond generous. I’m personally in commercial truck sales and I wanted a viable option for my customers using the 3.0 Duramax specifically the LZO generation. Unfortunately I don’t believe this is ready for the LZO. This may work 100% fine with the LM2 though. I’ve tried different settings but ultimately this causes a check engine light and even limp mode. I’m sure there will be updates and revisions down the road. So I’m hopeful this gets fixed! Again the team at AG Diesel has been great!
