DFM disabler for 2022 LTD

schindles · May 2, 2022

Hey all-

Just purchased my first truck ever. 2022 Silverado LTD 5.3l w/8 speed transmission. Based on what I’ve been reading, disabling DFM sounds like the way to go. Contacted Range and on their website it says that the only product compatible with my truck is their Pulsar LT. However, I’ve been told that my engine is the same as the 2021 5.3l w/8 speed. So, theoretically I should be able to use their Range disabler product for about $300 cheaper that the website says is compatible. Plus, I really have no need for most of the other functions of Pulsar. Can you guys tell me if my reasoning is flawed or if I am missing something? Also, how can you tell if it is really disabled (to know if the Range isn’t working) on my truck? Thanks.

Supposedly the Range doesnt work due to software changes. At least that i what the company told me when I asked this same question.

Well if the Pulsar LT works. It’s only another $150 about and you can change all kinds of settings with the truck. I think it’s the better buy. If your truck has anything over 18 inch tires. It’s speedo is off about 1 mph. My High Country is off by that. My wife’s traverse has 20s and it’s also off by 1 mph.

I think this summer I’m going to bite the bullet and send in my ECU and get the Diablo can tune. Nothing too aggressive but I figured since out of bumper to bumper warranty, and I love this truck, plus new ones are too stupidly high, might as well go for it.

Good luck with what you decide.
