True. Sorry, I hope it didn't sound like I was ignoring your results. I always seem to forget that Garrett does make non-ballbearing GT series turbos like the Gt37, Gt3571, Gt4082 and 4088, etc. Sorry about that. That's definitely some nice power for 16psi! I'm sorry if you've already mentioned this Yermancars, but did you say you weren't running an oil restrictor? I wouldn't think one is necessary since it's a plain bearing center section, though I guess one can never really be too sure until it's been done.
