    Why do you say it's dead lean?

    I don't see the o2 sensors or wideband data in the logs to verify that.

    And don't just blast the MAF/VE with fuel to make it not lean or rape the PE table to command some stupid rich air fuel ratio.

    If it's not responding to added fuel to the MAF/VE you have a real problem going on. Like low fuel pressure, vacuum leak etc etc.

    Do you have a wideband o2 sensor installed on your car??

    wideband on dyno reads 14.8 on my richest tune and stock and read like 15.6-16.0 on my first flash.

    Time to hook up a fuel pressure gauge then.

    Also add your injector pulse width avg for both banks and your o2 sensors. Make it easier to compare that data on the logs.

    Seems like you need to do a little reading, what fuel are you using? If you are using premium 91-to 93 octane, the first thing id do is set stoich to 14.1 across the board. That will already help richen it up. Like 5FDP said, do not rape the PE tables and add a bunch to the MAF and VE. Calibrating is methodical and has ways to make things right. Guessing is only going to hurt the car. Make one change at a time and do a ton of reading. If you really want more help and a hands on approach, give me a PM and we can work something out.
