My readings are about 19.8PSI which is actually ok. But the CEL P1107 that I'm getting doesn't seem to come from a boost leak it seems that the feed voltage to the map sensor is to low. I'm wondering if this could be because of the Zeitronix with all the sensors that are connected to the same ground wiring on the ECU, hmmmm. Just a wild guess, that is why I would like to try to disconnect the Zeitronix to start with then do a diagnostic measurement on the map sensor according to the Crossfire manual.
