So it's an engine thing, not a turbo thing, is what you're saying? The engine is full more or less (air-wise), it can't use or do anything more with any more air at that rpm range.

So with that being said, really any turbo setup would not make more power at that RPM range either, whether it be a stock turbo, EF2, etc. Because this is purely an engine thing, and the PTE is already packing it as full as it can get with air.
