I've been tunning for 15psi and then for 21psi. I'm pretty sure I tuned for the 15psi pretty well, keeping the same settings to run high boost. I get massive knock starting at around 3800 rpm. So I went and pulled the timing, seemed to be better but still getting 2.5 degrees of knock with only 6 degrees of timing or less. I'm not sure how people are running high boosts at 16-18 degrees of timing. Should I just continue to pull timing until it goes away completely? And also, with the second high boost log, past 5100 rpm, it started to buckle and stutter, and I noticed the af ratio got pretty lean, not sure what the issue is since all I changed is up the boost.
