    3800 Running extremely rich

    Got my 2000 Monte Carlo SS out of winter hibernation this week. Put in new 42# injectors, and made the Flow Rate changes.

    It's a 3800, with a paxton novi 1000 on it.



    Going for some runs, looks like my LTFTs are all -25, even at part throttle. Where do I need to do a bunch of the adjustments? Is it all MAF adjustments on this car?

    Yup, everything is pretty much MAF based on that car.

    Re-tune the maf for the injector change and see what it's like.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Correct, you need to rescale the MAF Calibration for the injecotors.
