    Question LQ9 wont stay running after FAST LSXrt 102mm tb/intake swap...HELP?

    Here is my current open loop tune to start AUTO.VE with:

    OLPreFAST.ctz

    The truck starts great, then dies a second or two after. If I hit the accelerator it dies quicker.

    1. Does that mean it is getting too much GAS or too much AIR?

    2. And either way, how do I go about adjusting for that?

    Log of start is attached below, disregard AFR for now because gauge was apparently off and needs to be recalibrated.

    LS1B_0178.efi

    3. Is there anything special I need to do in the tune with no MAF being plugged in?
