|Sorry but you are way off. You need to rescale every table, constant that references load by the injector constant. There are like 30 some. If this is not done you will have a lot of problems. This was posted elsewhere.

With a naturally aspirated motor and stock calibration, the load value will range anywhere from 8-10ms at WOT. Ironically that also maxes out the injector duty cycle for the stock injectors (not by coincidence either).
Now, let's keep the same injector size, so the injector constant (K) remains unchanged. But, let's add some boost, say 50% more airflow worth. This means the calculated load should now be 12-15ms.
But wait a second....the load variable can only read up to 12.75ms. Oh no, what do we do?
Simple, we increase the injector size (since we need larger injectors anyway to fuel the extra airflow), and change the injector constant (K) a corresponding amount. Now our new, modified load variable is back into a useable range and not maxed out.
Of course, changing the K value also means you HAVE to change all of the load references in the cal by the corresponding percentage. If you don't, things won't run properly.
You can Pm me for more info.
