Hey guys got a profec b II installed 2day at the jshop and on my Stock my99 WRX and its only boosting between 5 - 10 psi, the dude said that it was something to do with the stock solenoid, but i thought the solenoid should be disconnected coz the EBC ??? If any1 can shed some light on this for me guys it would be much appreciated or let me know if they have a Profec B II working on a stock my99 with standard ecu and let us know how u did it ??
