Well lads just looking for some info, what is purpose of 3 port boost solenoid and also is there a uprated 2 port solenoid or would i be better off getting a 3 port,
Some say 3 port makes boost a bit more stable and can make a car easier to map as a result, it removes the restrictor pill from the system too usually, its not something you can just throw on though, i fitted mine and was getting boost spikes until my map was tweaked
I got secondhand 3 port solenid from dave at stituning for my blobeye, got it mapped also and found it holds full boost for longer throughout rev range, you can get them new from the usual suspects, scoobparts, scoobyworld, rcm etc
