I could feel it on my'14 V8, but not at all on my '14 V6. I use cruise control religiously! Every time I hit 25 mph I hit the cruise and pretty much just accelerate with my thumb. I get way better mpg and mine stays in V4 mode more. I just got the truck because it looks sooo cool. If I could get a "range" or AFM device that would keep it in V4 mode, I would install it. I want the awesome looks of this truck, with the fuel economy of a Prius.
