I sold mine. Not worth it.
Step 1) Talk to Ray @ TurbotekTuning. He will hook you up with a better opensource map for alot less money.
Step 2) Hit up a strip club. Your friends are going to be alot more amused when you tell of how you blew $600 at the the strip club, rather than how you blew $600 on a stupid accessport that you sold after 8 months.
