Apparently 'chips' actually just plug in to the underside of the ecu in a falcon. If you hasve a looki at it, the ecu will have a sticker or cover over a plug on the bottom of it. If the ecu has the same plug on an I6 as the V8, then it will plug in, same with the T series to the XR8, just need to check it. Mind you this is merely what i have been told so don't take it as gospel. Surely a unichip installer could tell you if you rang them.
