Good question. Granted my car by no means is a DD and only see's the best of days. I'd like to see the reliability vs boost, since that is my biggest concern.

10psi on stock 112k mile bottom end. Motor can take it just the trans. and the 10bolt that you have to worry about.

you should specify whether you're talking about stock motors or built/bigger cube motors.

Most of my Procharged time has been on 10 psi. Driven everyday in rain, snow, hot weather, whatever.

That's good to know.. I was worried about the amount of psi on a DD.. If I ever find the money again to fab up a FI setup (getting ready to bite the bullet on a 9"), I was scared of running more than 5.. I guess a lot of it is in a good, safe tune also..
