Is the cam timing the problem, or something else?

It will wind up, but it seems lazy, have pulled it to around 5500, have tried adjusting the timing all over the place. I will be pulling the intake off to change it, so I will be able to check everything. I think I am going to order a degree wheel kit before I go much further. Right now I'm looking for ideas or suggestions. All are appreciated.
Throttle opens fully as well.
