Hi Walter,

I don't want to start a flame but what are u trying to say with the following statement?

>As we all knew, many of the blown turbos were on chipped cars (though some weren't). Big bummer, me says.

That those who chip their cars should?

A: upgrade their turbos as well, or
B: run their chipped cars at lower boost levels, or
C: not chip their cars at all (that takes the fun out of things for me)

I run no higher than 12-13 psi of boost on my chipped Porsche 951 (944 Turbo) and that seems to be fine (according to the Porsche gurus on the Net) because the stress on stock components is not as great as it would be at higher levels (15+ psi).

Since my 951 has only been chipped for the last 8 months (with ltd use because the S4 is my daily driver), one could make the arguement that it's only a matter of time that the higher boost will adversely affect my (BIG) 4 cyl Porsche engine. Please note that I had 120k mi on my 951 before chipping the car (I am the 2nd owner - car had 80k mi when I purchased it 1996)and it still has the original stock turbo from 1986. I will keep my finger crossed.

BTW, I still plan on chipping my S4 after I hit 50k mi (currently @ 45k mi) mark for obvious warranty reasons. If I need to upgrade the turbos (on the S4)for reliabilty, I will consider that.
