High rpm miss

[Dart7383]

So, I was stuck driving my '13 Nismo all winter. It got four solid months of boring commuter duty. 40 miles per day of cruising 45-65mph. I took it out for some fun last week, and I cant get it to rev. It acts like I hit the rev limiter, but this happens somewhere between 4500 and 7000 rpm. I had a set of oem spark plugs, so I put new plugs in it. I cleaned the mafs and throttle bodies. Nothing changed. It runs fine from idle to 4k. I am thinking possible fuel starvation? It is not pulling any codes. It has Stillen gen3 intakes, beluga short tails, and a south bend clutch. The old spark plugs all looked fine, I didn't notice any clues there. Does this sound familliar to anyone? Any thoughts would be appreciated
