Anytime you increase the performance of an engine ( in this case, crack up the turbo boost without any other hardware change, bigger cooling system, more oil capacity, ****** fuel injectors etc. ), you are putting more stress and wear to the engine, as well as drivetrain. It's sure will shorten the life of the engine no matter what. It's just the price to pay to have more power than the original engine was intended to do.
My car only has one year of the factory warranty left so I chose not to do it. But if it's a brand new car, I would just have it installed in a heartbeat. Drive it hard for 4 yrs and trade in the car and let someone else to deal with the propblem.
