Took it for a spin (out to a junkyard with some old Mercedes carcasses BTW) today. It peaks at 9psi of boost which, according to ForcedInduction, is perfectly normal. I would also agree with the other comment that there is a break-in period. It seems to have quieted down a bit, but I will still replace the U-tube seals as one of them is in really bad shape.

I forgot to do a 0-60 time on it today - I'll try that soon. If I remember correctly, that should be in the neighborhood of 16 seconds, no?

Thanks again guys!
