Blow-by on modded engine

[bleedcummins]

What do you guys measure for blow-by? Stock engine max spec is 10"(iirc), but what is everyone getting that has extra fuel, extra boost, extra power over stock? I measured summer of 2015 and at 20psi turbo boost I had 6", but by 45-50psi I had 14", I didn't check it at 65-70psi.
So wondering what other guys are getting and wondering if a rebuilt engine, would keep blowby back in spec or if it's just nature of the beast of a modified diesel

I have 3 blow by tubes on my puller. If the three of them each leave a spot less than 6 inches in diameter on my trailer, I'm satisfied :lolly: :lolly: :lolly:
