Yes. You are losing power and pulling timing.

1-3 counts of knock isn't really going to do anything, but something there isn't right if it's showing 1-3 through the entire pull. Post a log.

Shouldn't Evil Intentions Tuning be able to handle this?

I would consult your tuner, as ultimately if your paying for his advice I would run what he recommends.

if it's a random fluke, no big deal, but if you're seeing it most everytime I would go after that issue in the tune and correct it.

If its 1-3 all the way down it will just pull timing and make less power. Random 1-3's can sometimes make more power then no knock all the way down. But thats not always the case.

Well said, 3 counts of knock will pull 1* of timing so if it is happening in every log you should pull timing, if not the ecu will do it for you. This will make for a ugly timing curve and inconsistant results. Just my 0.02
