I get where your coming from. a lot of these pumps flow a lot of fuel in the 50 to 60psi range and I have seen them fall off at higher pressures once you start turning it up.i just want to see your learning curve and fun curve go in the same direction.No way to be sure about 1:1 until I get a log kit. But I can tell by the adjustments I had to make to the VE table that fuel pressure is rising with boost. The higher the KPa, the more I had to lean out the car. Light load and idle, I had to add fuel to compensate for the new lower fuel pressure in those loads. It all makes sense.
