Ive done it myself with MPPS lead and a more-bhp map. Ive got induction but no exhaust yet. They reckon about 240-250bhp but not had it on rollers yet. But it has deffo transformed the car.
Will get more once exhaust is in place. But I'm planning on ko4 conversion at some point next year or two (got to get house buying out the way first!)
