Does anyone know if the active fuel management can be shut off on my 08 silverado 5.3L?
why would you want to shut it off? and no i do not know if you can shut it off lol
i have a magnaflow cat-back system on it and when it shuts off 4 cylinders it sounds sick
makes sense, i do not know of any way to shut it off. I'm sure its something in the ECU (ECM) so hopefully someone on here that knows more about tuning could help you with a custom tune or handheld programmer that might de-activate the active fuel management. My truck however does not have active fuel management (I dont think any of the 2500's do)
There is an exhaust system out there that works with the active fuel management system. I dont remember the name of it, but you should be able to google it.
i think you can tune it off.
i have been told that the diablo sport "predator" programmer can shut it off, does anyone know for sure if this is true??
100% sure the Diablo has the feature to turn AFM aka DOD off. My buddy has the Gibson super truck cat back and had to buy a Diablo because of the tractor sound. I have heard the Corsa cat back is tuned for 4cyl and 8cyl but cost out the ass.
The Diablo DOES turn off afm or dod. You want part# U7194. If you go to DiabloSport.com and than to product and put in that part # it will show everything it can do.
i will check it out thanks guys!!!
