Just bought a new Chevy 1500 2wd, 5.3 V8 with Active Fuel Management. I have tried to lisen or "feal" the switch between 8 and 4, however I have not been able to. Is it that smooth? I took it for a ride today where I was on a steedy decline for over a mile. Cruise was on 55 and the engine was working very little. So I thought that is when it should kick in. Maybe I am just not hearing or fealing it. My truck is crew cab work truck so it doesnt have all the fancy features with buttons and driver displays, however is there a light or message on the dash indicating V4 mode? Thanks for any input.

 

its pretty un-detectible...i watch it on a scanner and can barely feel it when it applies

 

I guess it would feel the same as driving our trucks (stock)?

In all of the trucks I've driven in w/ this feature, I couldn't tell the difference ...the only difference that I could see was how much they spent on gas per month and how much I spent.... it was enough to make me cry.

 

Can you get a 1500 4x4 with that feature? 2500 4X4?

 

I just got a 07 6.0 extended cab and I cant when it switches either.

 

Any one heard of an additional program to add AFM to an '06?
