I installed a air dog unit--truck runs with lopy idle. I have a new injector pump installed with new regulator. I am thinking too high of pressure from air dog unit causing problems--any suggestions

and fill out your sig with what vehicle you have:thumb:new to this site please bear with me. 2002 lb7 Banks power economind unit and BD exhaust, banks intake unit, new injector pump and injectors. I installed an air dog unit and it runs poorly at idle. The fuel pressure i believe is to high. My guage indicates over 10 psi at schrader output port. the air dog does not come with adjustable pressure capabililty. I tried to contact air dog but no luck getting through. I am thinking I take unit apart and adjust the factory setting accordingly---what are you thoughts?
You need to change to an 8psi spring in the AD. Call them back, I havent ever had a problem getting a hold of them. I went from a 8 psi spring to a 12 psi spring a worked great.
