    Where is the wideband input? Everytime you hit wot, there is a lot of knock. STFT's are high, so it must be running lean.

    I have adjusted your VE Table and Maf based on your log. Your Long terms and short terms are all over the place adding up to 25% fuel. I smoothed out the VE table and increased it accordingly. Its not going to be perfect but should give you a starting point. load it up

    Had some other tuner look at it to and he said
    You’re getting 7 degrees of knock retard and total timing is only at 15 degrees when that happens. That 6 liter is capable of pushing 26 degrees on premium fuel and 19-20 on regular.
