Hi im very excited to be adding new toys to my car, but am a little confused. spoke to the tunner about adding a twin turbo setup to my car an he recomended adding a wideband o2 sensor and converting to a 2 band map sensor. I would appreciate any feed back on how to convert the map sensor and where the best place to get the materials would be and where the wideband o2 sensor would go on a borla exhaust system with h pipes.
