I'm running the .55 trim Garrett T-3 on my mildly-modded 603. It gives me plenty of boost by 2000rpm, wastegate is set at 18.5psi which it hits by 3500rpm, really nice low-end power from this setup. I'd imagine that you need some significant IP tuning to be able to use all of the air from the T-30 Garrett on a 617, 60-trim stock? Overkill.
It does have an annoying shreik from about 8psi-10psi, which happens to be where it runs at 75mph/3krpm, I need to find a way to quiet that down. Above that it crosses the 17khz audible threshold and I can't hear it anymore, probably pisses off nearby dogs though.
