2 or 3 port boost solenoid
 

hi im relativly new to the world of scoobys, and i was wondering what are the advantages of having a 3 port boost solenoid on my car as opposed to a 2 port boost solenoid?
thanks

If you plan on having the car remapped then it gives the mapper more control over the boost.

If this is the route your going down then I have one if you want it. Removed as I had an AVCR fitted.
