Yea sorrry, i edited my post, they actually are NGKs i don't know why i said desno's (i still have the spark plug boxes). So you're saying that i pulled so much timing out that i'm actually not knocking anymore, but rather, misfiring because of the low timing? That actually does make sense because i got 11 and then 36 successive counts of knock on one run and then 43 counts when i pulled 2 degrees from the entire map on the NEXT run. I'll do some logs and tuning with a map that i've saved from a while back, i'll post tonight them tonight...

When you tune other people's and your own car, is there some sort of limit too which you don't want to go beyond when dealing with the timing map @ boost pressure higher than 10 psi (say generally like 10 degrees)?
