its "ECU Flash", an open-source flashing software. I have mainly used it to deactivate DTC codes.

Anyway, PROBLEM FIXED!
Here is what I did.
1. I removed the entire fuel system from the engine bay, lines, filter, fuel rails, inejectors, regulator.
2. Cleaned all parts, blew air through all lines, blew compressed air backward through each injector while cycling it open/closed.
3. Reinstalled eveything, but I plumbed the fuel system differently. Instead of having the fuel pass through the regulator(Radium Engineering aftermarket regulator) , then through the rails, then dead-end at the number 1 injector, I now have the fuel feed going directly to driver rail, then over to passenger rail, then out of passenger rail and into the regulator and the return line connects to the regulator.
Two different ways to plumb the system. I have used the dead-end technique sucessfully in the past on some very high-horsepower cars(not subaru), never had a single issue.

So maybe I cleaned a blockage, or maybe its the new plumbing scheme. Either way, it is running smooth again. I guess I owe myself $25.
thanks for the help along the way.

I'm having the EXACT same issue! The only aftermarket parts I have installed is a short ram intake and new turbo inlet. Car throws no codes and I tried replacing the MAF as well.

Do you think I should do the fuel system clean or is it bad gas?

Tommy55 > the first thing I would do is test the wiring connected to the MAF and the MAP sensor, I have

had the connections break inside the pig tail or just before. Also just as previously posted, the first

question for you is: Is there a custom tune on the car currently? if the injectors are not scaled properly

then you may want to address that first before you end up wasting your time on needless testing.

when connecting the short ram / turbo inlet you may have damaged the connections
