Loss in power above 3500 revs

I need help identifying why my car has a loss in power above 3500 revs. It almost feels like fuel or spark is being cut. I confirmed the vvti solenoid actuates with 12v applies and cleaned the small cone oil filter below the solenoid. I also replaced the fuel pump and plugs. Does anyone have any ideas?
