ViPec (and all other standalones that I know of) can't/won't operate and read the Subaru factory front O2 sensor. One could theoretically move the wideband pre-turbo and use an EGBP compensation. I'm sure the OEM's have equipment to do this but the only one I've seen at the consumer level is the newer AEM 4-band UEGO controller that has an optional EGBP sensor and compensation kit.
