FLOW/VACUUM LEAK
When Monitored: Engine Running, during all drive modes.
Set Condition: If vacuum drops below 1.5 Hg with engine RPM greater than 2000 RPM
at closed throttle.

seems like this is a problem in the 05's that don't have the reflash done. it's usually found otherwise in conjunction with overboost codes. is this the only code that you are throwing?

yes this is the only code. at first it was overboost code but i did some vac line mods and now no overboost codes but everyonce in a while i throw p2074.it only happens once in three months if even that all i do now is reset the computer and it fine for a while but i want to make sure i am not messing up my motor.also if its not messing up the motor is there a way to tune this out ?
