My work truck is a 20,000lb '07 F750 with a 5.9 common rail ctd turning an allison 6 speed. What can i do to this thing to get a little more out of it. It's a **** starting off, and can't get out of it's own way pulling hills. I've had it since it was new and i take excellent care of it and it's always been this way. I just need a little something to keep me ahead of the pack, literally, my company runs 10 of these things around here and they're all identical.
