    Let know if I can get anymore out of this K04. Max rpm a little short of redline but 3rd gear WOT I get nervous that close... Maybe the three lanes filled by semi's on Freeway at merge in my mirrors didn't want to stretch to limiter. Turbo was replaced by PO. Pic may help to verify it is a knockoff. Running well, VersaTuner Base93US Grimmspeed Interrupt Tune, MAF cal done for Air system mods. 3 bar MAP. Looking forward to a turbo upgrade. Would be fantastic if more boost is still available though before that.
    See sig if any questions on mods.
    Bilstein B16 (PSS9) are this months $$$ upgrade though.

    3 Bar for a K04 you say? That log is not helpful. It doesnt even show MPH.

    Am I missing something? 70% WGDC and a 1.9 load? The k04 has a lot left in it but you don't have the supporting mods to realize it.

    Thank you, man you have busy cleaning up the forum threads (for sale especially!!!) I read and read and never found a specific example of expected data points.
    Response would mention what was missing, so this will be easy !!!!! Thanks

    Added as many as possible. Looks like this is normal. A different tune is next since this current one has a stock fuel pump limitation. With my hpfp I can add more air.

    Looks like a bad MAF cal to me. Those g/s numbers are way off what they should be.

    Looking for a better maf cal... The existing intake setup has no direct analogy to existing maf cals that have been posted in VersaTune forums. Going to fit curve better. Trying to use stft, ltft in my driving areas is almost impossible. So will keep trying.
