This is what I understand from increasing fuel pressure on a TBI.

-More pressure will support higher horsepower on modified engines.
-When when fuel pressure is increased, the BPW needs to be lowered to compensate for the higher pressure.
-VE tables will most likely need some tweaking

When I was reading through the comments on the $42-1227747-V5.9.3.xdf mask, I noticed in the scalers, under INJ - Injector Bias - Pulse Width Offset, there was a note:

Added to the total BPW. used to compensate for injectors that open slowly. As the fuel pressure is increased the injector takes longer to open. If you add fuel pressure this should be increased.

I understand the math for calculating the BPW change when fuel pressure is increased. Is there a math equation for finding out how much the Injector Bias - Pulse Width Offset should be increased?

Is there any other parameters, scalers, tables that should be looked at when fuel pressure is increased?

FYI, I currently have 15 psi for fuel pressure with the regulator spring I bought.
