Was looking at possible tuning options and really prefer the reversible nature of a piggyback. I was looking at the Switzer piggyback in another thread and noticed that it looks very much like the Race Chip piggyback. In fact, it looks nearly identical...

Race Chip:

The hardware is probably identical (assumption made based on the identical packaging) so that leaves the software as a potential difference. In the installation videos I noticed that the Race Chip wiring harness is also 100% identical to the Switzer shown below.
If they are the same exact unit the difference in price is significant between the two of them.
Update: Just found this video showing tuning potential of the Race Chip Ultimate piggy back. I am very interested in this product now...

Update 2: Wow. Just found it listed on the U.S. website for $769 with 1 day express shipping and 14 day return policy.
