    You need to post a log too and any modifications you have: Heads, Cam, ETC..
    The judgement of your VVE and MAF depend on your error log, that being said, the way your MAF curve flattens out up top doesn't look right to me

    I'm no expert, but it looks like you are trying to bypass the PE delay. I think you are backwards on your temps. You bypass the delay above 250 and below 400 degrees, If I'm reading the table description correctly. Now you do have RPM and other criteria correct, So I'm not sure if that will over ride the temps...
    For PE I think you need to lower the throttle delay below 70%
