Manual Boost Controller gone bad ??!
For some odd reason, my Hallman ES mbc suddenly stopped adjusting. For example, I got a 10 psi WG spring and with the Hallman hooked up, I cannot get more than 9 psi of boost with the Hallman mbc fully close, etc. Do these actually go bad suddenly?
I know its not the WG cos I put a 15 psi spring and it went to 13 (with hallman mbc in line)
I just do not understand how these go bad??? ....

Yep tried cleaning it etc. etc. Hallman emailed me and said it might be the spring needs to be changed to higher tension (???) which they apparently do sell. I am just gonna try a different MBC...
