i have a profec b spec 1 (original profec b) and im having a problem.....i need someone who has one to let me hook up my lines to their solenoid just to see if the problem goes away or not...dont even have to go driving or nothing.....the problem is the following: if u connect the boost controller the dumptupe stays open...it sounds like the car is on down pipes when it really has an exhaust....as the car is idling theres exhaust gasses coming out of the dumptube just as it would out of the muffler....if i block of the "out" port and leave it on the wastegate spring it goes away and the car sounds normal again....i need this asap so if anyone has one and is willing to help i'd really appreciate it....if you are selling it and it fixes my problem i will buy it.....
