Stealth Module - Chevy/GMC Duramax LM2/LZO 3.0L (2019-2023)

22 Chevy trail boss 3.0

Really woke it up towing a rat on medium felt like it wasn’t even back there I would definitely recommend stealth. One problem is it’s hard to drive on wet roads on high can’t get any traction and that’s at 1/4 throttle

GMC Sierra 1500 elevation LM2

I love the module, acceleration gains, drivability, performance, I have gained in 3 weeks of fillups around a average of 3.1 mpg, and noticed around town my average staying higher as well, love the product And the help with installation over the phone was awesome, so kind and helpful, guided me and a friend through it Thank you 🙏

Great torque and power curve

I was reluctant to buy a tuner for a 3.0 duramax. Hasn’t been one on the market till recently. Bought this and was surprised at the difference. I have 35” tires and I can break them loose any time. My power curve in the midrange feels way better. Better throttle response. Very impressed. Mpg went up by about 4. And I have it set on high. Can’t believe this little motor puts out so much power.
