Been massaging in some new timing last couple of days since i was getting some KR from hell. Figured id post a log and my tune for some comments. Generally i wouldnt post a tune since it took some time to get it right but I would like any veterans to give me tips if at all possible.
Thanks!
Oh and the couple KRs during WOT from the log i already subtracted on to the tune ive attached.
