this is what i used to use on my ego's, and got pretty good consistancy on good paint
1st, lube your regs with dow 33, and make sure there isnt too much on them.
lube your rammer with light gun oil
then i used these settings
LPR 1 turn past flush
dwell at 9.5 stock 10 tadao
then tune the botton reg(hpr) to attain velocity
make sure the ball barrel match is good, altho i used mainly a 693 without too many probs
finally make sure your batt is good.
This is my personal setup, and i am sure many others used different, but it worked for me, on 3 diferent ego5, and an ego6 and a sl66
the effieciency at the higher dwell is still awesome. But i am sure most ego's on that platform came stock with 9.5 dwell anyway.
