if you're running check valves and an FMU, does the stock FPR need a vacuum line? or can you just leave it?
i'm thinking it should still be connected for off boost/idling
my friend has the project 5.0 up on jack stands so I couldn't get the car out lastnight
still have to do all the finishing touches...
i've got no $$$$ so managment is lacking
gonna be running check valves and FMU unfortunately
buying a house takes priority over uberdata tuning
