All that it affects is additional fuel added to make up for any delay. .04 is ok if your original AFRs were good.

I use .10 with my 1200s.

The range given for them was from a low of .04 to about .20. I chose .10. It does not really matter if you stick to one value and then AFR tune with a wideband.

Yes you can, but add additional fuel on the PIM map until you AFR your maps. The larger pintel in the injector takes longer to fully open due to increase mass. That is why a correction value(lag) is used.
