MSX-150 wont go full throttle

[Paradise pontoon]

Have a 2004 MSX-150 jetski . Wont go full throttle. Runs fine at half throttle but thats it.Replaced System Module, PPU interface module,PPU and throttle body. So not sure what else to look at? Anyone had anything like this on a jetski? Its a Polaris.
Thanks

From my searching, it's probably best to ask your question on the Green Hulk forum. Your ski is a complicated one with a turbo. Finding compression should be about 125 psi, fuel pressure 58 psi and several other things.

Wish we had some talent to help
