Jemry, check you do not have to coarse a pitched prop.

Had the same props for years, not blowing smoke. had injectors done, new air filter, will check and replace fuel filter in next couple of days.

LOL, no it's normally on a trailer, looking more and more from what I'm reading online like a fuel problem.

If turbo engine, would take mixing elbow off and check clearance between turbine and turbo housing. If the gap is visibly larger then about .2 mm then you may not be getting the required boost pressure. Also a good chance to check the condition of the mixing elbow, they are prone to corrosion and worse case causing cooling issues. I would hope you are changing (or at least inspecting) your fuel filters each season and you will see any signs of bug that may be restricting max fuel flow.
