I was having the same problem when i was using the Nitrous. I swithed over to a MSD digital 6 and it has full power up to redline now. Check your igntion componets. Maybe its time for a new igntion?

The more probable cuase is the following: the engine might need some more fuel at the hi end. Before I did the heads/cam it was "runing outta steam" at the top of 4th. I bought an AFPR and bumped the pressure a bit. It cured the problem.
