I've had this 1991 galant VR4 for about 2 months now. It's pretty much stock in exception of the front mount setup, with 2 RFL blow off valves, and the factory blow off valve all connected and in use.
My question is, whenever i disconnect one or two of the blow off valves, it causes the car to not build boost correctly and hold at a certain psi. What could be causing this?
edit:: I guess I should also include, that when I disconnect the BOV's, I just take the hoses off of the BOV nipples and just block off the vac lines that were going to them.
