I had a VORTEC Super Charger installed. Ever since then the EGR Drive Cycle test wont complete. The performance shop that installed the Super Charger and associated custom tune originally said that EGR was turned off in the tune. So they gave me a new tune revision. Well even with the new tune revision the EGR drive cycle test still wont complete. They have since given me 4 more tune revisions and still each time the EGR drive cycle test wont complete. So now I am trying to do some of my own investigating. Using my SCT Flash X3 handheld and the LiveLink software from SCT I have done a data capture of all EGR parameters. I am hoping an expert can tell me if EGR is actually on because i doesn't look like it is...

The PCM data capture period was 10 minutes of various driving:

Metric - High | Low | Average
_______________________________
Commanded EGR - 0 | 0 | 0
Desired EGR Flow Rate - 0 | 0 | 0
DPFE Voltage - 118 | 73 | 104
EGR Duty Cycle - 0 | 0 | 0
EGR Error - 0 | 0 | 0
EGR Percent Actual - 0 | 0 | 0
EGR System Delta P - 21.9 | 3.2 | 15.3
Minimum Delta Pressure For EGR - 0 | 0 | 0
Pressure Across PFE Orifice - .18 | -5.8 | -1.3

Go to a different tuner. Avoid BAMA. With Doug gone only the name remains. Other than that, something might have been left disconnected. Also, get an oil catch can while you're at it to stop oil from going into the intake
