Turbo Timers?

I was recently chattin with my bro who has the WRX Imprezza and he mentioned the use of a turbo timer in my 1.8t....will it hurt my car if I don't get a turbo timer. I don't think I'm runnin that much boost to threaten the engine. I think VW would have considered this or put a turbo timer in the beetle if it needed it...or I could be wrong?

Turbo timer sound like a load of B.S. to me. Mabe he ment a shift light to tell you when to shit so that you get the maximum boost an horsepower from the engine before you shift?
