Message	the difference in low end. I very meticulously degree'd my stock cams to stock specs. They were only off a few degree's but I did see an improvement in compression after doing so. My compression ranged rom 145-155 psi previously and afterwards I had 155psi across the board. But it is possible that the other dyno with untouched cam timing resulted in slightly advanced cam timing which helped with their low end. These are the changes I made to each of my cams: Passenger side exhaust: Retard by 2.5 camshaft degree's Passenger side intake: Retard by 2.25 camshaft degree's Driver side intake: Retard by .4375 camshaft degree's Driver side exhaust: Advance by 1.5 camshaft degree's [ http://twinturbo.net/nissan/300zx/forums/general/view/2561773/I-am-more-inclined-to-think-it-is-cam-timing.html ]
