Went down to Holland Ct diesels dyno day in Ft. Collins and strapped it down. Put down 455 and 781 on a stock trans It kep trying to shift into fifth obviously locking it out with the DVT controls didnt work. looks like i coulda got a few more HP out of it if i coulda ran it up to 3800 like i had planned. I was pretty happy considering my log showed i only was at 83% throttle I was a little scared walking home. Gotta thank Danny aka 2500heavyduty for the tuning help, we tried to tune out some torque to make the ally last longer.
