curb fuel pressure

[madvette74]

maybe my bad luck, but I got 2 holley regulaters and 2 fuel pressure gauges, and I still have the needle jump up to 12-13lbs when I rev the engine.. is there a way I can change the spring or something in the pump to regulate fuel pressure, it's the holley blue pump.

Why not just put the stock pump back on to avoid all these problems? It's not as though an aftermarket pump is a performance 'upgrade'

believe me when I say I am regretting this.. I was thinking a little less power taken from the motor on the high end.... yea I know, what 10hp....

If you had NASA-level lab instrumentation, you MIGHT be able to detect 0.01 lost horsepower from a mechanical pump, just as you might be able to detect 0.01 lost horsepower from the alternator charging more to run the electric fuel pump; makes no difference either way, and the electric pump does NOTHING for "performance" - zero, zilch, nada.
