2008 Active Fuel Management AFM with 5.3L
Has a way been determined yet to extend the amount of time engine will stay in V4 mode so it does not go to V8 on the slighest incline?

RE: 2008 Active Fuel Management AFM with 5.3L
find a way to get more HP form the 4 clyits running on, it only kicks in as the truck need the power, so on any incline, or weight added to the truck it is most likely gonna go to V8..would it really makes sense to keep a 5000lbs truck running on 4 cyl trying to climb a hill, it would be working to death.

I have the same question as Boomer1, how can you tell if the engine shifts from 8 to 4 cylinders or vice versa? My IC doesn't have the listing for the AFM and the salesman says it just happens with no indication. I can drive on long flat roads and cannot tell the difference.
