Mine is flat as a board from 6200 - 7000. I shift at 6700.

Mine made max hp is 6600rpm and stayed constant till 68/6900ishrpm then lost about 10hp per 100 rpm.

My max power was 421/385 w/ LS6 intake, PPLS6 style heads, LG Pro Longtubes w/high flow cats, corsa indy catback, vararam intake, stock everything else. I also was at 100% duty cycle on my 22.4#injectors from 4500-6900.

I put some hand ported LS1 heads in place of the PP heads, added volant air bridge, 28.8 LS6 injectors, so I will let you know what it makes with the replaced stuff.
