Very common over here in aus IO540. Sounds like the guys you speak of thrash the engines. Compensation for higher MP usually means a lower RPM which is far more beneficial for any reciprocating engine. Also it's not as though the turbo is just bolted on, the engines are designed to handle the increase in MP.

The problems are usually poor fuel management resulting in hot spots (always going to happen with any old clunker) and shock cooling. They need very careful leaning and gentle power adjustment. Even in the ausy climate most turbo'd engines are reduced by 1 in/2min. Once set the only time you touch the throttles is to land or go around.
