Ported stock manifolds did nothing but help spool on the 8/9. My guess is the higher flowing exhaust is playing differently on the X since it has exhaust MIVEC (which only the X has), with minor changes to that I expect to get my spool back.

I fully agree. Already just in the back-to-back untuned comparison you can see gains of +9whp in some areas above 5,500 RPM which is a really good sign.
