im looking to run 18psi on the standard injectors using a rising rate regulator as advised by chris (scoff) but if the injectors cant fuel for it i will run 15psi. What i want to know is what do i have to do to allow me to do this? I have removed every little ad-on to the engine idle control re-circ standard boost controller etc... I will be using a bleed valve and the actuator arm to adjust boost and have a scoff modded ecu. I know yo have to adjust the afm to 650 ohms for a bar of boost but would i need it to be adjusted to more like 700ish ohms for 18psi or would that just not work? and is a dumpvalve about the right size for a bypass???
