    Your A0009 is very very rich. Is this a referenced regulator and raises with boost? What injectors are you running? Ditch using B3618 for enrichment and use B3647 so you can command proper out of boost numbers and ramp to boost.

    You are leaning out the main fueling because the MAF is not failing correctly. When the MAF isnt failed right everything will run lean. Some of the OSs do not like the DTC value on non emissions. Switch it to A:1 trip. Also, I would suspect the maf is gone completely?

    42 what? How is the regulator and rail setup? This will define the shape of the A0009 table.

    I think Team208 is saying to do something like this:
    - B3647: ramp this up to something like EQR 1.22 in the last column;
    - B3613: set this to 105 kPa;
    - B3618: set this to boost fueling (EQR 1.235 is maybe ok, EQR 1.26 is safer during tuning);

    Team208, any refinement on those value...?

    I’ll take a look at those tables when I get off work and try to do a few more test runs if it quits raining. I really appreciate the help by the way. This is the first boosted application I’ve attempted to tune.

    Do you have a manifold-referenced FPR (what Team208 is asking) above...?

    Measure rail pressure with FPR reference disconnected (remember to reconnect after measuring).

    42 lb/hr injectors rated at what pressure (and what brand are they)...?
