I think it's important to note.... the fuel pump and regulator are both in-tank units and it may be necessary to bypass the internal regulator and use an external with a 1:1 boost reference, and also drill a return line into the bulkhead. -- I think this step is unavoidable if you want a perfectly tuned engine. (You effectively loose fuel pressure equal to boost pressure) Although I'm really obviously in the dark about the factory computer and its capabilities.
Also in lower boost applications the loss wouldn't be as significant and most aftermarket controllers have the ability to jump bins to reach correct a/f ratio.
So...I'm not sure...
