Strangely enough...when I ran 87 tune with 87 octane--it pinged. Went with 87 tune, but 89 octane..ping gone.....ah, yes...I have my own SCT X3 with Brenspeed tunes...
Revised tune and it still pings like crazy above 4k. I may just use the
original Brenspeed tune and keep pulling timing until it's gone.
I just don't have time to call them right now.
