These guys make a great team. I was having trouble with my V3 tune and within 24 hours I had a revision tune that was loaded on my x3. Great customer service. Anyone out there who is trying to figure out what hand-held and from where... Brenspeed/ SCT is your best choice.

They are a good company but they limit them selfs to certain things like they will not tune anything they do not sell
