I want to know does the fuel pressure on a C20LET rise with the boost pressure. I know with some turbo set ups that they do but I ain't too sure about injection turbo cars and espescially on the C20LET. I currently have a power boost valve but I at the moment I have disconnected the vaccum pipe as I think it is flooding the system what with the throttle response from my programmable ecu as well.
I am thinking about just putting the vac pipe before the throttle so it will only rise on boost pressure and not have any response from the vac signal which I think also puts the pressure up as well. I will only do this though if the std C20LET rises fuel pressure with the boost.
Any one give some advise.
