Since the file only had some easily correctable mistakes + was simply out of date, I made it safe (set engine brake tables back to their factory normal), repaired and updated it, switched off the shutdowns and derates except for oil and coolant, then sent it back to you. Your welcome to use it if you like, so that you don't have to wait for Uni to troubleshoot what might be wrong.

I also lowered the turbo mapping/programming slightly to reduce the boost by a touch (but not the power or torque). You say it was getting to 38 psi, but the overall tables looked too high for a T800 in general. - I suspect your going to find either a boost leak somewhere, perhaps a CAC leak?, your turbo is a bit weak?, or some other air related issue? like maybe the egr piping broken somewhere? letting exhaust or intake gas escape?- unsure... so I put it to what should be expected just as a precaution so that it does not over-boost if you do find out why. The truck will make the same if not slightly better HP/torque for its power rating (~550-ish hp) with 36-37 psi no problem otherwise.
