Raj that was an old one not the one i sent to u ,,....

it was a JWT springs, changed them with a brain crower kit and BC272 cams

 

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.
