I'm an automotive enthusiast but somewhat new to the import world. I noticed one of the guys was selling a Vishnu Unichip flashed for stage 1 for 120 obo. sounds like a good buy, but possibly not for me? All i have is a Blitz BOV (previous owner installed) and i got in on the Bosal Catback GB. Is this Unichip not appropriate for me (until i get an uppipe.....etc. ) ??
