22lbs from PT88 too much? I have a forged 370 with a PT88. Made good power, 840-ish to the wheels at 22lbs.
Turbo locked up in about two weeks of driving. Send it back to precision, they are saying the motor is too big for the turbo, thrust bearing on the turbo went bad, and we should back the boost down to like 17 lbs..
does this sound right?

sounds like precision.......
and why I wont own one.
My first turbo was a precision......after two rebuilds and about 2200 total, sent it to another company. They said it should have never been built and was doomed to failure.
That was my last precision turbo. Funny thing is, I have never had any other "mysterious" failures ever since. Just my experience though.

ive run mine to 22psi and about 2 days later on the street it just locked up. they said the thrust went out. they upgraded to the new 360* thrust and larger bearing. I just got it back and will start it up tonight. 6 week turnaround. also they said it needed more oil. so i upgraded to a -4 feed. i was running a -3 no restrictor. i have a 370 also. i know the turbo has more in it. my boost controller was on 57% i would think 30psi is possible with it set on 100.
