Speedo way way off
Well went to old town this weekend in orlando and took the turnpike. Well running at 77-80mph on my 93 cummins speedo was really only 68-70mph and a good bit of throttle keeping it around that speed, what's going on?
Also at that speed the egt's were about 850-900, tranny was 150 and boost was 6-8psi.
