That sounds about normal with the line "ON". If you were seeing 43 psi with the line "ON" then you were probably in the 48-50 psi range with the line "OFF". The injector specs that are provided by manufacturers are tested at 39.5 psi WOT (vacuum line OFF). When you increase the fuel pressure higher than that amount it increases the amount the injector is able to squirt. This means that if you had 50lb injectors and increased the fuel pressure to like 55 psi then they would be rated to around 55-58lb injectors.its running at 30psi idling with the line on. seems low.
before i adjusted it, it ran at 43psi with the line on.
so when i went to drive it again it was waaaayyyy lean.
