Also, they are tri-metal.
I was assuming that it would needed since Nissan has various "grades" on their journals, both for the crank and the block.

i'm looking at the last dynochart and the power seems to level then drop off between 6200-6400 rpm. please correct me if i'm wrong. and you also stated that you have a port and polish by headgames, and full ferrea vavletrain right? i'm not saying those cams arent nice, but i just dont see them increasing in power to 7000rpms. btw, i like the trq curve though! EDIT: on the first dyno graph i see the power incease to redline, but just not in the second graph.

However show me another LOW boost map dyno chart that makes the power the way the BC did on my car..

I am guessing he used the stg 2 or 3 cams.
stg2 :
Adv.Dur. = 264/264
Dur.@.050 = 222/222
Lift(in) = .426"/.426"
Lift(mm) = 10.82mm/10.82mm
i think stg3 is 275º
(subscribing for dynosheet @ higher boost levels)
and LOL @ thread title change

i dont know what your LOW boost map is but this is mine at 15psi( my low boost)probably would have made more power if i had a port and polish on the heads. the low boost is the dotted line. the solid line is 18psi. all on 93 octane.
