Trying to dial in fuel.
Can someone look at this log and tell me what I should do. I have Intake, 3" catless turbo back, and obviously 93 diablo tune. My AFR on my wideband goes 11.7 from 3-4k, 12.0-12.3 4-5k, and 11.2 5-6k. It seems if the tires break loose it will sometimes jump to 13.0 for a quick second. I have added 16% fuel from 2-7k rpm so far. I have attached a log. I'm getting a max of 2.5ST knock and 1.5LT knock that starts around 3500rpm and fluctuates from there. Should I just add a tad more fuel or pull a little timing? I'm spiking 21psi and holding 16-17 on PCM controlled stock wga. If its worth noting in just replacedy upstream o2 that failed 2 days ago. The log has two pulls starting around 3000rpm. I ease into to.save my stock clutch. I think I went into 4th on the 2nd pull.
