    My new beginning tune w/ new injectors/ new setup as well

    Hello and Happy New Year!

    Here is my setup: SD

    408LQ4 233/250 618/595 113+5 Procharger F1A-94 3BAR DBC FIC1200CC INJECTORS
    It has a miss when first tap on the gas, So I'm guessing I missed a step when I set up my tune hoping someone can have a looking and give me some pointers.. Thanks in advance.

    Need P0103 set to MIL on First Error in order for the MAF to fail based on 0Hz Fail Frequency High. It's currently No MIL Light.

    Should have a vacuum-referenced regulator. The injector data entered is setup for non-referenced. Which FIC - Clinic or Connection?

    The injectors are Connection brand.

    Here you go. Injector data for vacuum referenced reg. I don't have access to your FIC data file, so used the existing data. Injector timing and Transient Min Fuel Mg updated. P0103 set.

    Be careful with those spark tables. Starting off a little too hot.

    Boost enrichment needs adjusted. It's going to command an eq ratio of 1 at 110kPa.

    I have a question. My spark table is from my stock file and what percent would you recommend I lower it?
    And as for my boost I was thinking of this adjustmet,

    It wasn't procharged from the factory. Spark isn't mapped very far above where an NA engine will reach. Have to anticipate more cylinder airmass.
