Modified injectors, especially those with larger nozzles (80% or larger), require custom tuning to correct the overfueling at idle caused by the extra fuel.

Do you have a chip or programmer that you can use for custom tunes?

Are you running the 180/100 files? Or the standard files for the stock injectors?

The 180/100 files should actually idle pretty well. We've used those for many years with very few issues.

So the next question is... How does it run on the standard Hydra calibrations?
