timing question (weed todd did)

[joel w]

Q: my sticker under the hood was unreadable and i had been running my timing about 5 degrees below (retarted) stock but when i set it to 10 degrees, i hear it knock or ping just once or twice under max load? is this the ecu just searching for the max advance and automatically retarding it untill there is no more pinging?

my dodge friend says its normal but i dont like it.. what do you ppl say?

i am sofa king weed todd did hahhahahha
