I did a fuel trim and made some small idle changes.
Looks to me like you have some kind of missfire at 4800... likely where you are making peak cylinder pressure at around 11psi. your timing is up around 23* she is making great power and the injector duty cycle is around 80%
Pull a couple of plugs and post pictures of them for me, if they dont have any signs of detonation we may need to look into getting a hotter spark to the plug. If we do show any signs of detonation, [small specks on the plug] we will want to go to a cooler plug or pull a few degrees of timing.
