Hey buddy. I was going over the ign map that you posted on a thread. I was curious as to how you arrived at those particular values. Also is the vertical axis based on TP values? I would greatly appreciate a quick response. I have been tuning my daily with Nistune for about two years and only recently started modifying the timing map. It is a redtop with S3 cams, gt2871r and 740cc injectors. Thank you kindly
