Will the stage 1 upgrade shorten the life of the turbo? With the higher boost, etc...?

Stage I on a stock setup will offer the highest performance with the minimum chance for damage.
Each addition of external "performance" mods will lessen that margin of error.
The newly announced Stage II upgrade will now use the stock turbocharger, and will give up to 260hp.
Since this is a speed density system, no matter what you do to the engine, it will perform as long as the data the PCM gets is in the range of the look-up tables programmed into it.
The down-side of that is that as the engine wears, "performance" add-ons are installed or any change that causes the sensors to report data outside of the range of the look-up tables in the PCM, performance will start to go downhill. This is not due to the wear, add-on or sensor age; it is a function of the PCM and the inherit shortcomings of a speed density system.
Hopefully DCX will provide the dealers with flash upgrades that offset the natural aging as the engine gets more time on the clock.
The main thing that will shorten the life of the turbo is too much turbo spooling and too little cool-down.
Synthetic Oil and proper cool-down are still more likely to extend it's life than the Stage is likely to decrease it; as long as they are followed in both cases.
