I bought a pm6 ecu off ebay, and I was surprised to find out it had a chip in it already. It's from Superchips, a company in the UK. They claim it will give 13BHP and it costs $295 lbs.

I did not buy the ecu intending to get this chip, but i'm wondering if anybody has heard about it, or if it's a good chip, if I will actually see any gains close to 13bhp or not?

I just figured, it probably will give 3 hp or so, but it's better then nothing?
