Pinging

Pump shot is good piece of advice. I went from the stock #31 shooter to #35 on my 600 after the cam swap in the 318 but more of a remedy for a stumble than a ping. I'm concerned about the detonation with such a low initial timing. Even a stock 360 I would imagine would like 12* or more. I run 16* initial & 34* total, all in by 2500 and the mill loves it. Any ping with vacuum adv disabled?
