Ive hear good and bad things about the BMS Powerbox. They claim gains of 10 hp but dynos show about a gain of 5 hp. Im more interested in the throttle remap and I am considering buying one. Ive also heard that it downshifts constantly and is jerky. Can anyone tell me more about the powerbox, experience with it, etc?
