    I added a Gibson cat-back exhaust system to my 2009 Silverado.When the AFM switches back and forth from V8-V4 it makes a "Jake-Brake" type noise thru the exhaust.I want to find out is there any way to tune the Active Fuel Management out.Thanks......J.H.

    I did a Trifecta Performance Tune, The AFM was made more aggressive for more mileage. So yes it could be set for less aggressive.

    I am not sure if that can be done with some of the other tuners.

    I've got a Gibson SuperTruck system on my GMC, so I know exactly what you're talking about! JennaBear and Black Bear Tuning can fix you right up with what you want to do.
