really no point on going past 25 degrees of timing with the stock lsj cams, they just dont support power past that much advancement

more than the average bear.

do not go off g/cyl for "boost" reference. this number can be skewed easy by maf settings.

for an idea.
120kpa is 3psi. give or take a few 1/4 lbs. go off the gauge for quick reference.

wow..thx..so basically to get the highest torque out of it you would put the same timing thru the rpm band or really close to it?
