so I have been having this issue lately when trying to get into boost where I keep getting knock now when I run a log I have noticed that my timing doesn't seem to go lower then 22* when its target is significantly lower in the targeted cell. AFR reads correct for what it should be around .3 away from target but its like the timing wont cooperate. I can run any log needed and post it up but some help with the wealth of knowledge on here would be greatly appreciated.
