I'll be getting an S-trim cheap off a friend and it just needs a bypass valve setup. He was using a Bosch unit but lost it. He was running about 10psi, I don't know much about the different psi rates for the valves, I see some are for 6-7 psi. I only plan on running 6-7 psi at most so can someone recommend one for me, what about a BOV? (flame suit on lol) I can't use one can I since I'm mass air? Someone educate me on this :SNSign:
