i can't look at the link right now because i am at work, but judging from the responses, they most likely have it on an engine dyno. there is no way that a UDP would produce 5whp. really, the only thing the UDP if for is the electronics in the car so changing it would would make the car run smoother but not necessarily make too much more power.

Thats definatly a engine dyno fyi. That makes some sense, it matches up with the cars who have been modded fully NA and this was done by a company who job is to make numbers. I would expect the numbers to be rounded up and slightly skewered, since they are going to try to get every last little bit out of it.
