This guy is selling some sort of device that basically does the same thing as an ECU upgrade, at a much cheaper price. He says 10-22 hp increase. 98.5% positive feedback on over 700 transactions is pretty impressive. Not to mention a lot of specific feedback that says it worked!

What do you guys think??
