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.

353 Hp from a chip sounds pretty high, even with all the other mods (DP's, cat back, etc.) - but regardless, I would find the shop closest to you that can flash load the new program. 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.

Hum, pushing a turbo 200%.. Humm. Sorry I just made it a rule for you.

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.

There is a high correlation, I know that it is statistically significant. Driving habits reign supreme, as always. I've you WOT stock constantly you'll fail a turbo, if you WOT a chipped s4 constantly you'll fail it sooner.
