I don't know how to scale a MAF so that doesn't help either. Lol.

    My personal car had the same mods when I first got the car. Never had any idle hunting issues. It is entirely possible that your ported TB isn't playing nice. If they are ported too much in a certain area, you will never get it right. I've had a couple different ported 87's(91mm eff) and the Mamo V2 is the one that never gave me issues.

    I got in touch with Mike @ Soler and I think even he is agreeing that the TB is looking highly suspect due to the log I posted where it started up. He thinks it may be binding in colder temperatures and then recovering. I think he wants to warranty it for me and exchange it for another at this point because the behavior is not normal.
