    What gives the '05 trucks more power... like some have the 310hp.

    Is the cam profile the same? I know the e-fans add a bit of power, but I'd assume most of it is in the tuning (spark advance and/or fueling).

    We had an 05 loaner while our 04 was in for repairs, and I found it the same or less power than my 04, But the brakes sure are different, it like nose dives ob braking big time.
