Any help is greatly appreciated!!! Hi, im running with an rx7 intercooler, sps manifold and de cat pipe, hks air filter, fcd and actuator, iridium plugs, boost controller and a few other mods. Im running between 0.9 to 1.0 bar of boost but what sort of pressure should i be running my (fpr) fuel pressure regulator at? either psi or bar is good ????????? Thanks, James.
