I’ve read several threads where guys have done one, or a combination of; increasing the RPM, bumping the injection timing and/or increasing the fuel on the L2501. Now, in theory, these changes should increase the power output of the L2501’s engine. However, it appears nobody has any means of measuring any potential gains from these modifications. Plus, there seems to be zero consensus regarding the reliability or longevity of these enhancements.
I did personally reach out to the fellow that turbocharged his L2501 since that thread hadn’t been updated in over a year. The tractor is still running strong with over 100 hours on the turbocharged engine.
