I'm going to try and install a Blue Chip APB box this
weekend and am wondering if the "small" RV275
injectors that I have will "limit" the amount of power I get
from a wire tap fueling box or does it make a difference. Also
will my HO VP44 be able to supply all the fuel at the boxes highest
setting ?

 

You will notice a very very nice kick from tapping the wire. The HO VP44 will supply all the fuel you could ever get through RV 275's, dont worry about that. Now when you get big injectors, really big, like 5's or larger, then the HO VP44 becomes a limitation. There are plenty of 500 HP HO VP44's out there though.

Although I don't have a wire tap box, my experience was that the EZ fell off fast above about 2500 RPM with the stock HO injectors. With no other changes than installing the DD2s, the truck would pull hard to 3200. The dyno chart shows that I'm above 300 rear wheel HP from 2200 to 3200 RPM now.
