When towing, I am sure that you can exceed your threshold of EGT's easily with a stock set up.

Well, not "easily", but some stock PCM codes will get over 1,250º under extreme conditions of towing a heavy trailer up a steep mountain pass at wide open go pedal. So if you don't have a pre-turbo pyrometer, then limit speed when towing up a mountain to about 55 MPH, or about eight-tenths of wide open.
With my excellent intake and exhaust, and the Edge Evo programmer set on "Tow", I can maintain about 60 MPH up the hill when grossing 17,500 pounds without too-high EGT. When grossing 16,000 pounds, I leave the cruise control on 62 and hang on while my BTS tranny downshifts and my hot-rod towing machine takes the hill. /ubbthreads/images/graemlins/warmsmile.gif
