i was running 12 and it went to 0. But we found the i/c to turbo hose loose. And changed the o2 sensor. It looked like hell, all the ribs on the end of the sensor were gone. But since I am running race fuel I thought it needed it. Would that i/c hose have caused this?
could have released and let the boost blow out there instead of going into the tb. For sure, loose hoses will cause a problem. Whether or not that was it, I cannot say..try it and see if it is okay now, I guess.
