Message Here is the deal. I have hooked up the greddy profec b. I thought it was working properly.. but I cant adjust it. I have read up on it.. but I read something in the manual about a something that may need to be bypassed. I have taken a few pictures... to see if I am correct.. so.. here goes. BTW... just for gerneral knowledge.. at first I ran the hard plastic line and was told that didnt move enough boost for the greddy to read right... so I switched to a 4mm black vacuum line. It keeps spiking at 15-19 psi. So I removed the profec and put in a straight line to run stock boost.. it is hitting at about 10 psi.. is that normal? Also... in the pictures below do I need to remove that solenoid just above the turbo's? Do I just plug them off? the second picture is of the location of the valve and how I bypassed it.. 2 of the blue lines are just hanging there...
