My 5.3 is free
This little piece of technology has been 100 percent , completely , and without question a great product. From the minute I plugged it into my 2008 Silverado crew cab this thing has delivered. My truck now runs like it should. My AFM is off and I love it. Can you imagine the issues that go one when a V8 truck has to think OK now I'm a 4 cylinder , now Im an 8 cylinder . The things that the transmission has to accommodate. Well those days are gone. As an aside my DOD lifters that have to shut off and on are working all the time thus providing lubrication . I first heard about the lifter issues affecting all vehicles with AFM and DFM at a gas station about a year ago from a guy who took his chevy into a shop to have it disabled via a computer fix . I heard about these from a mechanic and that was it. My truck is so happy and now so am I.

Used
The box is battered and the unit was loose inside the box. Plugged it in and only one LED light is on. Smelled like it ran rich. 2017 Chevy Tahoe with 20l miles. It did stay in V8 mode. Defective if nothing more than LED lights not working and probs my used. Sending back. Will try again with a direct order from the manufacturer.Update: I ordered one direct from the manufacturer and the box and item is clearly brand new. The unit has a clear plastic protective vinyl on it which the unit above didn’t have. Works like it should. Seems like Amazon resellers are selling a lot of used/returned.

I was having lifter problems got it fixed at my own expense that is why I bought this arm disabler
I tried this on my 2014 Sierra with a 5.3 litre it does exactly what it’s supposed to do keeps in 8 cylinder making the truck run a lot smoother does not seem to shift and jerk all the time like it use to it did not affect the fuel mileage at all I am satisfied with this product and would recommend it for anyone who is wondering about it

Perfect fit.
I was a little bit worried about using it at first.The shifting is so much better and my fuel mileage is just about the same.I just feel like my 2014 truck runs smoother shifts better and that's what I wanted.I didn't like driving down the road and feeling that pause every time it jumped from 4 to 8 cylinders.
