Well, I got to experience my first dyno today, holy crap.
Attached are the results. A couple of circumstances, I asked the tech, who had not done many rams, to watch the boost and try not to let it get too close to 8, so he ran it up to about 5800 and backed down. The damn truck was still pulling hard, but the boost was giving me a pucker factor and I didn't feel like blowing it up, so we let it be. When I eventually get around to doing drop in pistons I'll do a bigger pulley, but I'm happy for now until the suspension and brakes get some attention.
We did three runs, and could have done a few more but I was about to have a stroke so we backed off and based on the results I was more than happy. I pulled fuse F26 to kill the ABS/EPS, and showed the tech how to manually lock it in 4th and 5th, it kept up and down shifting depending on how he approached the run, so it took a while and I don't know if we ever truly got a locked in reading.
Dyno was a mustang. We didn't do any dyno tuning, I just wanted to see what the truck was putting out with Jay's tune.
