What is happening on this dyno? Help
looking at those graphs, the horsepower curves are relatively smooth/flat once it gets up there, so I doubt its any slippage or converter issues. In my experience, itll spike,drop,spike in some fashion if something is slipping and then grabbing back. The torque curve does fall flat at higher RPMs, which is not unusual, the somewhat backtracking look to it does look off. Not sure exactly what would cause that yet looks like nothing drastic happens to the HP curve in either graph at the same time, but it does have a very slight blip there it looks like (pics are a bit small to tell for sure). So maybe a stumble in timing or fuel or something along those lines?
