Yellow Check engine
Since i Bought my Mini Cooper S 2007 with 42,000 Miles i'm 2nd owner i bought it with HKS Blow off and when i floor it the gas pedal like in 4,000 RPM the engine power goes dont know where... the Blow off doesnt sound, and its like a safe mode because use more gas like black smoke not all the time but i know. i want to know if anybody here got the same issue/ problem... lot of people tells me that i gotta remove the HKS blow off, other people tells me that the Blow off its just vacumm and i doesnt matter, others tell me that i should do a Ecu Reflash because i put Alta perfomance parts... and im confused... i cant race... i just watch... 
Got any idea?
