18SHO was kind enough to send me a couple logs, he is good to go. His logs actually show near perfect fuel pressure 2000+psi.. and almost no knock.. less than +1KR (.8 iirc) at worst.
I think it was a polish notation issue.. SCT reports adding spark with negative knock values and pulling spark with positive KR values..
18SHO tune looks very well done for the fuel he is running.
