That is what I was thinking. Either you got a AP2 ecu or mabie they flashed it with an AP2 flash, I am not sure if that would happen but if it is hitting a rev limiter at 8k than that is an ECU problem. If it just runs out of power at 8k than that is a timing or valve issue.

Are you hitting fuel cut at 8k? Or something else..

If its fuel cut, sounds like an AP2 ECU.

I cannot fathom any reasons why they would rebuild the engine and then throw on an AP2 ecu......

where would they have sourced an AP2 ecu from ? What purpose would they have for putting it on?

Me neither.. but that doesn't mean it didn't happen. We really need to know what happens at 8k before anything even resembling a conclusive response can be given. Hitting the fuel cut is a pretty recognizable feeling.
