Awesome product
2022 Silverado pre-refresh, RPO codes L84 (5.3L V8) and MQE (8-speed transmission). Pre-refresh means Global A architecture and compatibility with the Range RA003, whereas trucks after that ("2022.5" and after) have Global B architecture and require the RA007. Range Pulsar LT can be used on just about any but it's more expensive. Lots of youtube content on all these devices. What a difference. It's like a different truck. Even in L7, which is supposed to disable DFM, the drive was clunky. Much nicer with this device, and the auto-stop is fully disabled with it installed regardless of the dash button. GM removed the display to show which cylinder mode you are in but based on the improved drive and the auto-stop, it certainly seems to be working and worth the money. I did also buy an OBD2 splitter so I can use a reader at the same time, and so that if I unplug this RA003 frequently I am not wearing out the factory connection.

Good money spent!
Cannot say enough good stuff about this. Use it in both my 2LT Stingray and my 3LZ Z06/Z07. Great product. Performs as advertised. Both cars benefit from staying out of V4 mode.

Expensive, but does its Job
Works as intended, using it in a 2018 Camaro SS

Range RA003B, excellent product
I am in Australia. Ordered through Amazon. I read as many reviews I could find. Used in the Chev 1500 Silverado for a week or so and found it to be as advertised. Can't fault it at this time.
