Bernd, the pressue offset I was talking about has nothing to do with the LT
or ST trim. It's a simple pressure read that causes an offset in the WOT
table. Certainly an issue with the later trucks, though maybe not with the
97-98 models. Don't know when they added the logic.

Don't know exactly what you mean by rising regulator. If it's a simple 1:1
then all you're doing is countering the boost pressure and again 19#
injectors are pretty much done(gone static) at 325 rwhp, and injectors
really shouldn't be pushed beyond 80% duty cycles for reliable performance
anyway.
