CCW with a 3/32" allen wrench slows when (in hg amt) the curve amt (8x2=16 degrees) starts by tightening the spring so it takes more vac to overcome that tension & there fore at what amt (in hg) the curve ends so in effect once you are in the curve by tightening the spring (CCW) you have less adv at any given in hg amt so likely that would quell any pinging if it did ping exp cuz we are very close on the amt. you would monitor this in eveyday driving under varying RPM/throttle (load) positions
