tuning question

[ptlogan77]

Okay...

40,000 miles into this new tune, running hard up north, eh!
The truck runs good, but on long pulls, as I go above 1500RPM the pyro starts to rise above 1050 pretty fast, and the oil temp rises above 230 pretty quickly as well.
I'm forced to pull hills at 1400-1500, to keep the temps in check, and I'm afraid of long term bottom end damage by not being able to run at a higher rpm on hard pulls due to the temps.
On flat ground and short hills I'm able to run at 1600-1800, but even then I see the oil temp rise. I also am virtually unable to use the third stage on the engine brake, as it rises above 32psi immediately. second stage is fine for most hills, but stage 3 would be nice at times.
With the cargo that I am hauling (live seafood), I have to run the engine during stops to keep the air pumps running. I always idle up to 900 rpm, and have no slobber or other idle related issues, but would like to know if the tune can be optimized for efficient running during high idle to reduce the risk of liner polishing and fuel wash.

The tune is a great improvement from stock, but I feel a few tweaks are now needed to allow the engine to run at a higher rpm without temperature issues, and allow usage of the third stage on the jakes without potential damage.

any input regarding these concerns would be greatly appreciated.
