Alright guys i bought HP tuners a while back and played with on vista on a Virtual system on My Mac Computer, well it crashed (just my virtual system not my mac) and i got mad and bought a new comp just for tuning, off newegg.com they have lots of stuff at good prices and bought this and it came with vista and i bought XP to install but its a pain to do the swap and not 100% sure how, my question is is it worth it or just keep vista?
