abunda_amazon_reviews Bought this for our 2013 Tahoe 5.3L. This was the cheaper alternative to the popular more expensive tuners. Ohhh its so nice to have a whole engine available with no hesitation and much better throttle response. Other reviewers have stated that it killed their battery after the vehicle sat for a couple of days... well the box clearly states that if the vehicle is not to be driven, then the device should be removed because it may cause parasitic draw on some vehicles. Other reviewers have stated they saw blinking lights and then nothing... yes when the vehicle is started the lights do blink and then there is a solid light that you don’t see unless you hold your hand under the device to see it lit, which is great because I was worried about a glaring annoying glow coming from under the dash. I can leave this plugged in on my truck and it just works. No need to unplug and replug everytime the vehicle is stopped/started. The biggest thing that tells me that is the engine management display which shows wether its in in V4 or V8 mode and current MPG, it says V8 all the time now. Smoother idle, no more shudder. Ill update if I experience any problems. ***update*** 3-25-18 To date there have been no issues. The truck was finally able to sit undriven for 4 days with the device still plugged into the OBDII port and there were no issues with a dead battery. Some other reviewers had an issue with it creating a parasitic draw, but I am happy to report that I have yet to see that problem.;;Reviewed in the United States on February 11, 2018;;5.0 out of 5 stars;;Let there be power!;;Trigger8318;;;Unit seemed to work on first drive then did not keep engine in V8 mode. I believe item was older version of Range Technologies firmware. Bought new one direct from Range with the latest firmware and works perfectly. If you want the EFM disable device buy direct from Range Technology web site to ensure you get latest software. Amazon should not fulfill this product for this seller IMHO.;;Reviewed in the United States on February 26, 2017;;1.0 out of 5 stars;;Buy Direct from Range Technology Site;;John;;;Bought a 2011 Chevy suburban with 125,000 and noticed it was drinking 2 quarts of oil between changes of 5k miles. My mechanic told me to order this tool. He said GM 5.3L active fuel management has a lot of bugs with valves -lifters failing. This tool keeps all 8 cyl running while at idle. Fuel mileage is still about 16 mpg city and 21 hwy. This tool stopped the engine from using or burning oil between changes. I would recommend to any GM 5.3 L active fuel management engine;;Reviewed in the United States on December 28, 2018;;5.0 out of 5 stars;;Saves Oil and Maybe An Engine Rebuild;;Troy Frady;;;I hated the way my 2017 Chevy Silverado drove without this product installed. I put aftermarket exhaust on my truck and every time it shifted down into the AFM 4 cylinder mode the truck bogged down terribly . Terrible drone from the exhaust system inside the cab. It ran like crap to put it bluntly. I put this product on the truck runs like it is supposed to no more of the 4 cylinder nonsense. If I wanted a 4 cylinder truck I would have bought a 4 cylinder truck. The mileage is very close to being exactly the same. It runs so poorly in that 4 cylinder mode that it feels like it is sputtering and running like crap. Not something that is conducive to getting better mileage. Note to GM get rid of that Active fuel management system it stinks. But range technology saved my truck from GM's hyge mistake. Well worth every dollar I spent on it.;;Reviewed in the United States on September 24, 2017;;5.0 out of 5 stars;;I hated the way my 2017 Chevy Silverado drove without this ...;;rnodler;;;I’m using this device on my 09 GMC Sierra 1500 5.3 and I noticed a huge difference on performance. I’ve had this truck for almost 2 and a half years and it feels a lot stronger and more responsive when I press the gas. Before it would hesitate a little and after about 1-1.5 seconds later the RPMs would jump up and would force the engine a lot I’m guessing it was because it was switching from V4 to V8 because now it doesn’t hesitate at all and it’s causing less strain on the engine. I will update this review if I notice an improvement to my oil consumption which is why I bought this device in the first place. Overall, I’m happy with the purchase. It was a bit expensive ($222 with taxes and shipping) but I hope it pays off.;;Reviewed in the United States on August 7, 2018;;5.0 out of 5 stars;;GMC Sierra 1500 feels more responsive;;Amazon Customer;;;Seems to do what it says it does. Been using for a month and no issues. I used to get 17 mpg average in my 2018 Silverado. Now getting 16.9 mpg over the last two tanks. In my opinion, this is a small price to pay for improved throttle response and less switching in and out of 4-cylinder mode. It actually makes me a bit mad to think that GM is putting AFM in all these engines and it doesn't even improve the mileage for the average consumer. I would have opted for a performance tuner but I didn't want to risk my warranty. My only suggestion is to cut out the LEDs. I dont really need my feet glowing blue at night. I'm considering covering them up with electrical tape.;;Reviewed in the United States on December 30, 2018;;5.0 out of 5 stars;;No codes thrown yet and wont void my warranty.;;Casey S;;;Worked fantastic for 7 months then quit working. UPDATE!!!! I actually unplugged it, and plugged it in and it works again. Apparently needed a reset. It is still working. My oil consumption was improved in my 2008 Avalanche from using 1 1/2 qts in 4,000 miles down to 1/2 qt. with 120,000 miles on vehicle. My Ave MPG went down from 15.5 to 14.5 though using this device. I liked the way it works, smoother acceleration and deceleration . I will contact Range about replacement;;Reviewed in the United States on March 8, 2018;;4.0 out of 5 stars;;Improves oil consumption, but your MPG will go down a little.Truck drives better with it though.;;yamihoo;;;works like it should. made a world of difference on my 2017 Silverado regular cab. not as jerky, and my fuel mileage actually went up 1 point since I installed it...worth every penny ..;;Reviewed in the United States on April 3, 2018;;5.0 out of 5 stars;;works like it should;;Dawayne mckinney
