Passenger right side kick panel. If there is a black square sticking out of the ECC then it has a chip. My bet it does because my car barely ran without getting it dyno tuned with a supercharger.
I hope all that oil didn't mess up the MAF. Seemed to be excessive oil going that way.

Well I can handle the MAF because it was built by Pro -M Racing and have all information engraved on the MAF. It's the other stuff I'm a complete newb on.
I've cleaned it twice now, along with the dry pro-m air filter. I also cleaned the heck out of the supercharger piping too. I guess I will call pro-m tomorrow about new MAF? I tried today but they are eastern time zone and already closed. So I had oil coating everything several times now this as week and now it runs like butt. I'm going to try MAF.
See if you can mail them the electronics out of the maf or the whole maf to test bench it. It will only add and extra day or two. Don't throw all kinds of money at it just yet.

Ok, not sure if I over looked it but for the pcv this is what I have always done for forced induction: Cap the pcv, remove the tube between the valve cover and tb ( cap both ends ) put breather cap in place of oil fill cap.Never messed with the oil separater non-sense.
FMU is a fuel management unit that goes in line with the return line. Basically raises the pressure to make up for injectors that are to small. Band aid imo.
To tell if the car has been tuned assuming it still has the stock ecu, remove the passenger side kick panel and pull the ecu out. There is a port opposite side of the harness, if anything is plugged into it that means it has a chip.
Does the car have 1 fuel pump or one in tank and one inline? If one or the other isn't running it can lose pressure under load. Has happened to me.
Have you checked the impeller on the supercharger? Is there any oil on it? How about the discharge tube?
One more thing, where is the vacuum line from the fuel regulator going?

I am going to have to wait until tomorrow to check all this out. So, I am going to check every vacuum line and it's not the stock ECU. There is an box hooked up to it opposite of the harness. I knew it was tuned. I don't think it would run right with stock ECU? Like I said this car was running great, mid 10's, at the track last fall. Now I change oil and it went to hell. Plus, the owner gave me the dyno sheets that I decided to loose during the move to the new house. I should have stuck with a basic 331 without all the fancy stuff. lol

Well I can pretty much guarantee changing the oil was not the cause of your issue. When you say box what do you mean? Can you take a picture?
What I do know is the AF gauge by Innovate I installed this winter is reading more lean than it did before at idle. Then when the car would start acting up it would go from 13-14.5 to 18-23 with the RPM's bouncing between 1500-2500. Pro-M will run diagnostic on it for $50 so I'm going to start there before I start guessing and replacing parts that don't need to be replaced and the $$$.
It has one fuel pump on the outside of the tank. Aeromotive. The impeller had no oil on them and the discharge tube was cleam. I'm going to check the vacuum line tomorrow after work. The wife dragged me to the farm so she had someone present while she rode her horse, so my night was shot. lol

I'm betting the previous owner bought a calibrated maf in lieu of a tune since it has the Pro M
That is the V6 data trouble port (OBDII) and isn't functional on the GT. The DTC you want is in the engine bay on the passenger side strut tower between the tower and firewall. The ECU is behind the passenger side kick panel.
