Fascinating. This flies in the face of anecdotal reports that stock cams and springs can make significant top end power. JWT springs are significantly stiffer than stock but about 1/2 as stiff as other brands (Ferrea, BC, etc). I wonder if that contributed to varying power at high boost on my old engine. The new engine has a full Ferrea valvetrain so hopefully won't be an issue. I sent you an e-mail reply. Your logs don't look that bad. e-mail me back.
