. . .The true test of a CP3 is to provide fuel very close to 1:1 with what the ECM is asking for. . . With the right product, you don't need special programming to get rail pressure, you just need a capable pump. . .Having to "TUNE" up the pump, shows lack of its capability, having to tune down a pump indicates significant reserve capabilities. . .
^^Excellent explanation^^
I think it's great that someone on the ragged edge can use an electronic module to squeeze everything they can out of a mild pump. But, it seems more like a band-aid fix for the underlying issue.
Greg, With the new 85% pump do you still need the DR. P to see rail pressure above 25k or so?
