John advanced the cam timing. Is that what you mean? He played around with that until he felt they were right. A/F was obviously adjusted, but there wasn't really too much else he really could do. It was tuned from an s200 module and then transferred to my s100. Then again, I only know what he told me. He spent a good while making sure everything was set right, so I have confidence it wasn't the tune.
For those of you thinking it was the tune..
