    I assume since your already tuning your VE that you know how to do this. What I do since I don't know of any way to force it into one partucular mode is set all of your O2 airflow modes the same (450-550mv or whatever you will be running them at) - allow it to go through it's rich after flash issue - when I see it's in fuel block 6 and fuel trims are no longer moving around, I'll run it through the gears once then bring it back to idle and only then start datalogging for corrections. Long roundabout way I know, but it gets consistant data...

    Not sure with that compression and NA if you will see great low end throttle response without really retarding your injection timing and advancing your ignition timing quite a bit.

    Hope this all helps. Now time for me to go back to work...
