    I feel like I am going crazy but it feels like when driving up long steep 6-7% grades if I set the cruise control for 65 I can go 65 the whole way. If however I just use the gas peddle the car bogs and slows enough to get passed by semis (maybe not that bad but it feels like it). Is there a rational explanation for this behavior?

    I have a 05 also thats feels like that but I am sure it's just the cruise control doesn't care how much it mashes the gas but the driver does.

    I am begining to believe that that is kind of the case. The driver is limeted by the floor the cruise is not?
