At about 20 - 25 psi is where the 5000 comes alive and cleans things up nicely. From there, it get up to the 60 psi range REAL fast and I have the wastegate set at approx 72 psi.

The 160's are definitely more than the 3000 can clean up, but the 5000 can handle it pretty well.
They keep the EGT's in check well too. I haven't had any problem with EGT's getting over 1250, even on hard runs like that.
