Open source tuning alternatives

I have an 06 wrx and it has a downpipe and the secondary air pump delete, so it needs a tune and the CEL cleared. They don't do emissions where I live so at the very least I want it out of limp mode (I need my cruise control). It seems that my only option is to get an open source tune, but all the Tatrix Openports are on backorder. I have a COBB AP but with the EPA crackdowns I can't clear codes with it, let alone find a tuner who is willing to do it for me. Any suggestions or am I SOL?
