Ok a few days ago i posted a question about fuel pressure. I pulled the vacuum line off the reg, plugged it and adjusted it until it read 39psi vac OFF. with it connected at idle its about 32psi, full throttle is 39psi. sound right??
no problem. it is usual for the car to idle with 32-35 psi (when set at stock pressure with the vac line off). as you know, at WOT there is very little vac (almost nill) so the reading should almost be spot on with where you set it initially.
