Thanks for your input!
If there wasn't a big boost leak "somewhere" I probably shouldn't have a problem with DSMLINK reporting that I'm ok running at a ~18/1 A/F, but when I richen it up to where DSMLINK reports close to 11/1 the car bogs and back fires?
This leads me to believe that the Mas is measuring Air that never makes it to the motor, there by giving the symptom of running ok while that lean?
Does this make sense, or am I way off base?
I'm really trying to diagnose the weak power, strange loud noise and weird DSMLINK reading symtoms to get this car back on base?
TIA.....
