Default single shots wont idle
needing some help in a bad way, recently put a set of 180cc%100 nozzle single shots in a 02 SD, truck runs great other than im having an issue getting it to idle, as soon as she kicks off she starts loping real hard and wont stablize unless you feather the throttle a little, once its stabilized it idles just fine , did a data log and it looks like its bouncing from 100 to 0 on mass fuel desired, just looking for some direction if yall wouldnt mind

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?

as soon as it sees enough rpm to fire off it drops duty cycle down to almost nothing and you have to play with the throttle to get it to stay running, after that it idles fine but if you hold it too the floor and let off the rpm drops down and then dies, watching the data log it shows the duty cycle try too pick back up after the rpm and icp have already dropped down too far to stay running
