Colderweather86 Posted July 11, 2020 Share Posted July 11, 2020 Just got my truck back from the dealership. The engine was replaced under warranty at 44,212 miles. Intake lifter in cylinder 7 failed and tore up the cam, which sent metal throughout the cam bearings. I want to disable the Active Fuel Management. How is the Range Technology AFM Disabler(Holley product)? Quote Link to comment Share on other sites More sharing options...

HK GUY Posted July 11, 2020 Share Posted July 11, 2020 I have a 2017 Sierra Denali with the 6.2, bought it used with 27K miles. I installed the Range device and have not had any problems in the 1500 miles I have used it. I drive every day and haven't removed it. I've also received the OnStar update and it hasn't recognized the device. Sent from my SM-N975U using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

Kincer Posted July 11, 2020 Share Posted July 11, 2020 I use a Superchips programmer, the reason I went this route is I needed to be able to adjust for the bigger tires, anyhow I've had my AFM turned off for over a year now and have had no issues, as a bonus my speedometer is right and my truck runs better.
