    I lock out 5th when towing anything more than 5k lbs. I find it uses less boost and I get better fuel economy.

    Engine light is from the rear O2's. Some of my tunes have them disabled and some don't. No biggy.

    Only real difference around this point would be heavier Valve springs. I would like to shift at 6400-6500, so I would set the rev limiter to 6700.

    The porting on the heads and larger turbos allow it to still make decent HP at the higher RPM. I've confirmed this at lower boost levels.

    We'll see if I can get this issue sorted out, if my theory still holds out at higher boost levels. It may not make any more power, and if that's the case, I'll cap the revs at a lower rate.

    They are the stock cams, so built for torque. You can get away with a little more out of them if you mess with the Cam timing via tune.

    Same speeds and reset the mileage for the last 350ish miles. No trailer, but truck weighed 7136lbs when I hit the scales with cargo, passengers and almost a full tank of fuel.

    Not too shabby.

    I'm guessing with no report he is still chasing the misfire?

    But it's just a guess

    Everyday is slow, if I am the one determining the pace.
