    Wow. I was hoping I didn't overshoot but those changes I did from the 7 minute log didn't help with the trims much at all. Try this one and see how it does.



    EDIT*****

    Use this one; it has new PE settings

    THE VERY CURRENT ONE-NEW EDIT-2.1pe.hpt

    More MAF & VVE changes. That was a good log, this one "should" feel a little better driveability wise. We may want to check with some of the more experienced guys to see if it would be wise to turn off COT since you no longer have Cats.

    No cats; right? Are the Downstream o2 sensors removed from the vehicle?

    This one has COT disabled along with all DTC's related to 02; sensor 2 set to NER. COT disable.hpt

    I know. Was attempting to correct two things he may have an issue with in post #25 that he may or may not see in his tune.
    Do you see what was changed?

    I appreciate you guys chiming in. I'm using Version 5 of Editor, so if you're using an earlier version, then possible I cant see. Other than putting COT settings back, i cant see anything changed when comparing files; unless I'm overlooking it. Hoping a new log will show improvement for OP.

    Awesome! That's what we were after! Do a comparison between the file you started with and the one you ended with to see what all was changed. That way if you need to do any adjustments in the future, you will have an idea of where to start. Glad it worked out for you!
