It was just alarming to see it drop so fast to 30psi. i think i changed pants after that. 
The lowest i saw it was at 20 psi at 175F. (5w30 conventional currently in the car) |
Not sure about that one. I think you'll have to ask IAG since they claim to modify the oiling system. I wouldn't sweat those pressures since you're not beating on the car yet. If you're asking if they're indicative of low flow I couldn't say.
FWIW, the factory service manual specifies 7.3psi minimum at idle and 73psi minimum at 6k rpm, both at 176F.
