Welp, did some stuff to the truck and gave it run to see what it had. I was looking for alittle more but that will come later. I had the trans built and got a new tune. I need to get a lift pump and do some exhaust upgrades to get where I want to be. That will be a few months down the line. I didn't get a chance to log the runs and wish I would after I was done. I'll be working on the tune with the tuner and hopefully make some progress soon. I'll be running the NHRDA event this upcoming Saturday simply because I haven't raced the truck yet and curious as to see what it will run. It's still a work in progress and want to make 500hp. Not too concerned with ET at the track, but a 13 second pass would be kinda cool for me. Biggest number was 433hp and 793 trq, it was the last pull.

why did they have it run so many times? after the 2nd or 3rd pull it was probably heat soaked anyway no need to keep running it. the truck needs time in between runs to cool down

They had quite a few trucks to get on the dyno. The operator was willing to let me do whatever I wanted but he said not to take too much time. I ran the first tune just to see what it had. I was more interested in the big tune I have. I agree with the heat soaking. That might have effected the numbers on the last run or 2. When I go up to BD in May, i'll only be running 1 tune. Give it 2 pulls and see what happens. This was basically a shake down run just to see how the truck was running and see if anything was obviously wrong.
