It's not rocket science guys (hope that doesn't sound arrogant). Trickle off 2 inches of MP for every 1000' on descent. Do it smoothly as you would with an engine that is not turbo charged. Plan to arrive in the circuit with around 20 inches on the tap. It's all about cooling. If you need to give it a skinfull at this point it'll be ok. Like everything do it smoothly. Albeit a long time ago we never cooked a donk through ignorance. Look after the engine and it'll look after you.
