Works perfect! Highly recommend.
I had 2 Suburbans with the AFM Cylinder deactivation 5.3L. I traded them in because the fear of them going out without warranty.I trade them both in for a 2020 Cadillac Escalade 6.3L also with the AFM cylinder deactivation with CarMax and 150k warranty.I purchased this device to ensure my engine doesnât go out by deactivating the system.Ever since I installed it my MPG increased by at least 4mpg (I kid you not), the engine runs way smoother, it doesnât hesitate like it did before, and it has always stayed on 8 cyl.I have only used it for 2 months but so far it has performed flawlessly. Mine doesnât lit all the LED lights but only at the very beginning and then I think it only keeps 1 on or so. (Havenât paid much attention).I never take it off and it has not killed my battery or alike. It is installed on my daily driving car.

Just buy it! It works! Thanks Youtube!
I want to start by acknowledging that I am not particularly knowledgeable about vehicles. I bought my 2019 Chevy Silverado because I needed a truck and assumed that, being one of the most popular trucks, it would be reliable. Unfortunately, I was mistaken. Iâve experienced numerous issues with the truck, including problems with the transmission, air conditioning, alarm, and horn. The situation has progressively worsened, with the truck stalling, running roughly at various speeds, and exhibiting strange shifting patterns.I took the truck to my local mechanic, who advised that the problem might be related to the vehicleâs computer and recommended visiting a dealership. Despite having a 3rd party extended warranty, I was anxious about the potential costs, as warranties often do not cover all issues.I came across this device on YouTube and was initially hesitant due to the low cost. I considered opting for a even cheaper alternative but decided to invest in the more expensive one, hoping it would address the problems. I am pleased to report that this device has resolved nearly all of my issues. The air conditioning still has some minor issues when idling, but it’s significantly improved. Most importantly, the strange shifting, vibrations, and other performance issues have been largely eliminated. The only remaining issue is slight vibration during shifts between second and third gear, but it is not nearly as severe as before.While I cannot guarantee this product will work for everyone, it has proven effective for me and likely saved me thousands of dollars in dealership repairs. Itâs definitely worth considering if youâre facing similar issues.

Works awesome
It is just plug and play. A bit pricey but you know what. I plugged it in, Started my truck and no errors/warnings and now always in V8 mode. So far no battery drain I find. I have a after market all SS dual exhaust and when just riding along it sounded like a bubble machine. Awful. Now always V8 and back to sounding great all the time.Thank you,Paul

Works and didn’t drain battery
I purchased this for a 2015 Chevrolet Silverado with a 5.3L V8 engine. Shortly after purchase I took a road trip 1,500 miles, it performed flawlessly and kept the engine in V8 mode the entire trip. Not long after that I went on vacation and left the truck at home for 3 weeks, with the module plugged into the OBD port, on purpose. I had seen comments that on some vehicles it may drain the battery if left plugged into the OBD port and the vehicle isn’t driven for an extended period. I left this plugged in for 3 weeks while I was out of town and when I came home the truck started right up, it didn’t drain the battery by any noticeable amount.The only problem I noticed is that the monthly OnStar reports from the truck contain less detail and include a statement: “We were unable to successfully complete a diagnostic test. This issue may be caused by an aftermarket device plugged into your vehicle’s diagnostic port.”Shortly after I started the truck after the 3-week vacation, I got a full report from OnStar, but other than that, the reports I get don’t have OBD related data (tire pressure, fuel level, etc.) and just state that OnStar can’t get that data because of an aftermarket device plugged into the OBD port.Other than the OnStar issue, it works great, the engine runs very smoothly and the transmission shifts smoothly. I got 16.5 mpg on the highway with the module plugged in, it is a very heavy (6,000 pound) 4X4 truck but it is rated at higher mpg than that on the highway, not sure if that 16 mpg was from the module keeping the engine in V8 mode all the time or not. I just got the truck and never took it on a highway trip before I put the module in, so I don’t know what it would have gotten by switching to V4 mode at highway speeds, I can’t compare highway mileage before and after.I am happy with the module and I am hopeful that keeping the engine in V8 mode all the time will avoid the problems that eventually happen with the lifters and associated components in the system that switches between V8 and V4 modes, there are a lot of reports about that system being problematic.

Definitely worth the money!!
Does exactly what it says! I have a 2021 trailboss with the 5.3 10 speed and it’s like having a completely different truck. Shifts better and has way more power on demand. Disabled my start / stop. The light is still on but it doesn’t turn my truck off anymore. Awesome product!

Worked like a charm
Easy to use- just plug in and go. Buying a 2nd one for my husband
mike rhoadsDecember 30, 2024
works flawlessly
Works as expected and since installing my GMC truck runs constantly in a full 8 cylinders…. I have already replaced the lifters in the engine once at about 100,000 miles and its expensive. I believe this will save me from having to do it again in another 100k miles. So it will be a good investment for a poorly designed GM motor

After spending $3500.00 repairing lifts on my GMC motor I purchased this product. It was simple to install and works like a charm to prevent motor from shifting to fuel management. I have been using this product for just over 1 year now and have not had any further problems with my motor. Everything is running smoother than ever. Highly recommend.

Great product
Dale BDecember 30, 2024
Does exactly what it needs to do, and I don’t find that it drains the battery any noticeable amount even when parked for a while. I quite like the LEDs on it as well, not too bright but enough to remind you that it’s working.
Tanya EarlDecember 30, 2024
I have only had this installed for a couple days now. So far so good. What a huge difference. No more slobbering in V4. Stays in V8 as it should. I have noticed shifting is even better as it was shifting hard down into 2nd. A lot smoother now. I gave fuel mileage a 5 so far as I really donât expect much change. I will update progress once I have been using it for a bit and really get a feel for it. So far worth the money!!Update: Iâm still in love with it. It has not drained my battery at all as I leave it plugged at all times. Fuel mileage has gotten better as well. Donât even second guess it if you are looking at getting one. I promise you wonât be disappointed2nd Update: have been almost using for a year to the day and still a great product from the day I bought it. Buy it!! You wonât regret I I promise you!!
