Review on 🔴 Enhance Performance with Range Technology RA003R Active Fuel Management Disabler (Red) by Rob Rogers

Purchased for my 2017 GMC Sierra Elevation. I've had this hooked up to my machine for a month. For the first week or so I turned it off every time I got out of the car because I read it could drain the battery. Now I just leave it on. To be honest I think for those claiming that it killed their battery while sitting it was probably just a coincidence. So far I have no complaints. He does what he has to. Allows your V8 to work like a V8. The only downside is that my gas mileage is down 3 or 4 mpg (some claim their mileage is improving), but that's for city driving, not highway driving. But it doesn't really bother me. You can disable V4 mode by going to L5 (on GM trucks anyway), but you'll have to remember that every time and you won't have overdrive. Just plug in and forget. I was able to get a good discount on a used Revain. The packaging was damaged and the item itself had light scratches (actually a hairline). Not so hot what's up. It works so far and has a cool red LED when it's on.
