Scotty or others:
2017 Silverado 4x4 with 5.3L, 23K miles. I bought it with 22K miles. Should I install a plug in device to disable the AFM feature? I'm not worried about the lack of power, but I've read that the AFM system can compromise the lifters at some point.
What are the potential risks associated with disabling the AFM system, versus the risks of NOT disabling it? Which is better for the health of the engine? Again, I'm not very concerned with mileage or power, just the mechanical considerations.
Disabling the AFM is the way to go.
My Pulsar LT is coming in a few days. Can't wait to disable the afm/dfm and the auto stop/start in my TrailBoss
Installed the Pulsar LT in my '21 Trailboss. woohoo...
Sounds great but $500? Yikes!
It has a lot of other great features I'll be exploring as time goes on. Yeah, it was a bit less expensive over the holidays, but when they had them "in-stock" I wasn't in a position to buy it.
Hey, thanks for the links.
I'm sure there's a work around for it. If I were you I'd go to youtube, and also look on forums for that truck. Luckily its a Silverado, so its a common truck and people know alot about them already. & You are correct, that cylinder deactivation leads to engine problems. Ill admit it does improve gas mileage on the highway, the system is good for that, however Id recommend anyone to disable it. The money saved in gas doesnt offset the cost of the damages it can cause.
- Just out of curiosity, its it a 6 speed or 8 speed?
It's a 6 speed auto.
Nice that things way better than the 8. Yeah look into disabling it. Also a side note, my brother bought one of these new in 2017. When covid first started it hardly got driven. When we would take it out, the transmission would feel a touch odd for a few minutes. But once he started driving it more frequently it went away. Just a quirk about those we encountered.
Yeah. Mine had unusually low miles when I bought it, then I let it sit almost the entire winter. I mainly use it to tow my camper and boat, just a few times per summer. Got to remind myself to take it out and drive it more frequently.
I had mine programmed out at a local tuner who also did a dyno tune. I don't notice it NOT being there! I've put over 100,000 miles on the truck since it was done. Truck has 239,000 on it now. Most of my driving is in-town and I average 15-16 mpg. Also, I have noticed NO lack of power, but that could be because of the professional tune.
Which model year?
Sorry, 2014 Silverado 4x4 5.3 w/ 6 speed auto.
Never use Seafoam in a 4cycle engine, per Scotty's video.
I just received the Range unit from Amazon. I haven't had a chance to use it yet.
