Kohler ECV 730 - bogs under load

power and ground are ground are good. I ended up getting the Kohler diagnostic software and I am seeing that the engine wont stay in closed loop at high rpm. could this be causing the issue? also seeing on the software that when the engine goes into "power enrichment" is when the engine starts having issues. if i lower the rpm until the engine comes out of "power enrichment" mode, then it smooths out.
 
Some engines don't look at the O2 under full beans. I don't know about yours. Power enrichment I would think, would be increased rpm's or engine load. Sounds like more fuel is being dumped by the computer.

Are there any computer upgrades offered for this?
