Well the regulator sucks ya, the engine rocks it is a Honda. Bosch has no idea what is going on because they said the compressors are to new and they don't know what to do. I have to drive an hour and a half to a repair center because the centers around me are certified for electronics only not compressors or lasers. The guy i spoke to at a service center sounded awesome and he will check it out tuesday. The thing runs constant so the emergency valve kicks on every time the engine fires up to fill tanks. I used to love bosch i had bosch everything, but this compressor has been a nightmare. i should have waited until local places began to carry the compressors. I would love the compressor it has just given me to many problems to ever like it again.
