    Nearly any engine can benefit from a catch can. Piston engines produce pressure in the crankcase (basically the lower half if you picture from the crankshaft down) as the pistons pump up and down. If that pressure were to build it can reduce ring seal, hence the purpose of the ventilation system. Because of emissions reasons, however, that pressure cannot be vented to the atmosphere, so the manufacturers have to route it into the intake manifold so that it can be burned in the combustion chamber. The gasses from the crankcase carry emulsified oil that coats the intake runners (producing that sludge you see when you remove the manifold on a high-mileage engine), and degrades the octane of the atomized fuel entering the combustion chamber. In other words, it's killing the octane rating on that big tank of premium you just paid for. The vehicle's ECU will protect the engine by reducing timing, but performance suffers, and this is even with a stock tune. The ECU reduces timing any time it sees detonation, and it can sometimes be excessive. Adding a tune can aggravate the problem in the sense that you won't be getting the performance that the tune was designed to produce.
