chris, 1250 is actually a little more than you should go.
1250 is where damage may occur as the pistons start to melt, turbo damage may start at 1270.
I keep mine under 1200 at all times.
I usually start backing out when it starts over 1100.
Boost, 12 is a good number, just watch you don't overboost at high RPM's.

Usually one flat is more than enough, but pumps do get weak over time. Also injectors get weak.
I personally don't actually like to bottom out the fuel screw either, but I have never had a pump that did not put out more than enough fuel before it got to the bottom.

OK, since you twisted my arm....
Yes, it is a dump bed also, but the tool boxes and stacks don't move when I dump..
Here is a link to a picture of my truck on the way to work in the fields,

This is a bigger version of my avitar.
Well it was raining, so the fields were a little soft.
I guess you can also see why I have limited slip in both axles, did a body lift and only run mud tires on my truck.
