Review: Range Technology Is The Best - This product works Great!!! Keeps your vehicle running on 8 cylinders all the time!!! Better gas mileage, I have no more oil consumption!!! Well worth the money!!! Thank You!!!
Review: This device works. My mileage actually improved a bit, someone at GM should explain that one to me. - This unit really works. My new 2018 Silverado 1500 ("e" model) was running well before I plugged it in the OBDII socket, but I wanted the option of disabling this V8-V4 mode because of what had happened to my friend's 2011 Sierra 1500 (excessive oil consumption between scheduled oil changes due to worn rings on an otherwise meticulously maintained truck. This was traced to a lack of proper lubrication in V4 mode, an issue supposedly fixed since in the newer models). I just couln't afford to take any chances at having to go through an engine disassembly so soon in my truck's life. I mean, how long have they been messing with V8s? They should have left these engines alone instead of messing with cylinders 1, 4, 6, and 7. Since I do mostly highway trips, my mileage has actually improved, not by much, but it shouldn't have if you believe the GM hype. You really have to wonder why all this V8-V4 complexity was added to a perfectly good V8 if as, in my case, my mileage improved!!! The ONLY thing I miss at times (easily fixed by shutting down the truck and just unplugging it from the OBDII socket) is some engine compression braking in hills from the V4 mode. It helped me maintain a set cruise speed going down some hills with a light 2000 pound trailer load, and the fact that the engine no longer shuts off at stops or red lights (the "e" model has the Lithium battery pack and induction motor to spool up the engine under these conditions but it won't do any of that while this particular unit is plugged in). Other than that, I have the V8 I expected now, the mileage is fine and hopefully I won't have issues with failing parts in cylinders 1,4,6 and 7. The added complexities of these otherwise old V8's should be a cause for concern. They use a special camshaft ground differently just for cylinders 1,4,6 and 7, they have a higher-volume oil pump, and a pressure relief valve to handle the incessant oil/computer controlled operations of the intake and exhaust valves in these 4 cylinders and this device just stops all this from happening without reprogramming anything. I could be wrong of course, but I think the pressure relief valve should have no issues handling the changes for the life of the engine. The rest is literally put to sleep while this device is plugged in. If you want to take your truck in for maintenance, say while it is still under warranty, just remove it before going into the stealer. They will never know. Hopefully I'll never have to go in for expensive repairs due to failures with cylinders 1,4,6 and 7. Make sure you get this device with the latest firmware as it is now totally stealthy to Onstar's big brother monthly reporting. Range Technology has done its homework. I don't work for them, I'm just a happy customer and would recommend this to anyone just wanting back the V8 truck they thought they bought.

### ⭐⭐⭐⭐⭐ This thing saved my 5.3 Silverado!!!!!
*by G***. on February 13, 2016*

Researched the oil consumption problem on my 2008 Chevy Silverado 5.3 with Active Fuel Management, and found that when truck goes into 4 cylinder mode it begins to use oil to the tune a quart every 1500 miles. Decided to buy Range AFM disable module and it works great! Oil consumption is virtually non existent with 85K miles on the truck I change oil every 5 K miles and surprise the oil is still there. It runs strong in constant V-8 mode which has not effected overall mileage one bit. One thing I noticed that you have to check on information center once in a while to make sure unit is working because after I let the truck sit for a few days with module plugged in I noticed it was not working. I then unplugged the unit and plugged it back in and it worked, this occurred twice in a 6 month period. If vehicle is not to be driven for more than two days I unplug the module and haven't had the problem since. This unit is well worth the money spent to save my engine from damage from the GM blunder of Active Fuel Management, which in my opinion is inexcusable disaster inflicted on what in my opinion is one of the best trucks ever made."Product Update 11-23-16 my truck has 93k on it and today the truck began shifting very hard... I thought maybe transmission was letting go but remembered someone commenting on how the Range module was causing this with their truck. My solution was to disconnect Range module, then connect code reader to scan the system no trouble codes found. Then I cleared system just to be sure and installed Range module again. Everything is fine shifting perfectly I assume there is a firmware update for this problem.
