engine management is on, took the car into ford, they said its coming on due to the high flow sports cat, only way they can sort it is by changing it all back to standard which is not happening as the car came with a £1700 receipt from powerflow for the full system and cat, spoke to simon at sitech racing, says a stage 1 revo map will sort it and give me 360bhp, (350 at the moment) due to the mountune kit,
any thoughts folks?????
