This is off of my 07 Sti that I'm trading in. It will come unmarried and ready to flash your Ecu. The base maps will stay on it. I'm almost positive that this will work on all 04-07 Sti but I may stand corrected on that.
I'm looking for 450 shipped or best offer.
I'm even considering trading it for an unmarried Accessport for a 2011 Sti seeing as that's what I'm trading my 07 for.
