PBX does not add HP it just tricks the ecu into believeing the throttle is wide open at 100% 60% and 30%
By the throttle being open at 100% it feels ballsy but the reality is, it isn't more HP it is just opening the throttle sooner to give a better throttle response.
However, it does beat stock throttle and is peppier.

Do not expect much of customer service/support from BMS though, they are the biggest assholes in plain english.
