That sounds more like "turbo normalized". IE, the higher you get from sea level, the less dense the air. Horsepower is a factor of how much air/fuel you can get into the cylinders. At elevation, you get less air in the air so you need to also reduce the ammount of fuel to get a proper combustion ratio. This all adds up to less power available at altitude. Turbo normalization makes the engine think it is at sea level when it is at 7-10K feet and crams the same ammount of air in as a sea level engine would get. It is not a 30% HP gain, it is just not a 30% horsepower loss that the non-turbo engine would experience at high altitude. It also dosn't put any appreciable additional wear/tear on the engine that a system that boosts the pressure significantly above atmospheric pressure does.
A properly setup turbo has virtually no "lag" and power is fairly linear to RPM when under load. The beauty of the turbo is that it is more dependent on load so when you are not loading the engine, the turbo is just ideling along. It is also using waste heat(exhaust) from the engine where a belt or gear driven supercharger blower has a power demand from the engine even when you are not needing the power gains that it can provide.
