I think that all top notch ECU flashes spin turbos up to 17psi (is over twice as much as factory default) so regardless which one you go with, the life of your turbos will be equally shortened.

Woah now, the jury is still out on that one. I tend to agree that the working the turbos harder will make earlier failure more likely, but no one has offered definitive proof that chipping reduces turbo life expectancy as a rule.

APR had a shop close to me so that's why I went with them. If GIAC is closer, do that, if ASP is right up the street use them.

All the chip tunes are great bang for the buck.

I'm not going to get in an argument about this. There are plenty of people on here that have been running chips way past the normal life expectancy of the turbos without any problems.

Your argument is purely speculative, no matter how logical or self-evident it appears to be. As I said, I tend to agree that it follows that working a turbo harder causes it to fail sooner but there is no guarantee that this will be the case for every one that chips their car.
