110-111 with A/C off
Fast as it would go.
PE COMP and DD1's I was close to redline anyway so the ECM cut fuel back. Boost was about 25-30#,, EGT (not accurate) was around 950* and F. P. was 6#
I tried going faster,, but, no go. I had the pedal all the way down for about 10-20 miles,, but then "slowed down" to about 90-95 as the motor was under less load and RPM.
My 3500 with Fiberglass top (camper) is extremely stable in the triple digit speeds. It is the most stable vehicle I have driven at those speeds.
The only thing I was afraid of, was either a tire failure, or melting the front wheel bearings.

P. S. For that trip I went 62 miles in 42 minutes,, that's an +80MPH avg. speed.
