2008 f115 high speed skip

My outboard skips/misses at the 4500-5000 range. runs fine at all other ranges. The odd thing to me is when this problem is happening, the rpm guage jumps forward instead of falling.
These items have been checked.
Changed spark plugs
Changed fuel injectors
Cleaned vst and replaced filters
Changed ecm ($$$$$) even though it was a used part
Replaced cranking battery
checked fuel pressure
Any help would be much appreciated
