I will let you know for sure.
I have the v8.
This was my thought. I pick it up real cheap and could put it on ebay for more than I paid for it with no problem. I like to be able to switch back to stock and the vector tune with their cable giving me the ability to switch is about 600. Also it has to be better then stock. I will probably unload over the summer and get a custom tune but for now this will hold me over.
