Epprom tuning option???

[Boxersix]

Maybe I'm just blind and haven't come across what I'm looking for while searching these forums but what options exist for tuning the stock PCM for boost right now?

I'm not talking pre programmed units based on other peoples setups(Ie ECUTune stuff) but rather tuning options to allow an end user to adjust settings according to their needs. Windows or Linux based stuff, doesn't matter to me. Someone I talked to mentioned some Linux based stuff but I forgot who and what the details were on that

I'm opting to just run this thing off an OBR E6-C but want to explore any options out there with the stock PCM first before ditching a fairly decent OEM setup.
