The scaling of the injectors allows the timing table airflow to be scaled in half as well

But for any one wondering the same in the future here I'd a good write up
GM Gen IV Calibration Scaling - Injector Dynamics I know it says Gen 4 but same should apply to Gen 3

Basically, do what this article describes and look for any other tables that involve airflow or torque...including the trans tables! For the spark tables just copy/paste the rows(HPT)/columns(EFILive) as described. Do not simply scale them by 50%.

When the injectors are scaled 50% any thing and every thing to do with air flow weather it be in kpa, psi, g/cyl, lbs, etc it has to be scaled 50%. Also, your not limited to 50%, you can scale any percent 1%-99%
The article uses 50% for simplicity.
