Seen a 1st gen dyno in Indy (IRP), looked just like my truck, only less HP . Guess I should've taken the late Pastor Bob's advise of not doing too many things at once. Changed injectors, intercooler/aftercooler and timing (pump gear advance, ksb locked). I'm hoping it was just too much timing and or small turbocharger. I've got the pump gear advanced a tooth, and the pump head still almost up against the head. I also stuck a cold beer can between the power steering pump and injection pump (against the ksb) to make sure the wax pellet, or whatever the term is, was at the cold start point. Then unplugged it. This way nonIC'd style, the pump would be locked in advance.
423hp/801ftlbs down from 450hp/918ftlbs. Not what I was looking for, but I'm gonna back off the timing and try a bigger single charger (Pro52).

I will say I made more power at a higher RPM compared to my 450hp dyno run last year at Scheid's event. Scheid event I made 400hp at 3000rpm. 350hp at 3200rpm. Little to no HP beyond 3200rpm. This run I made 423hp at 3000rpm, 400hp at 3250rpm, 350hp at 3500rpm. Run out to about 3800rpm .
