If your going to fit cams then buy Piper re profiled items. New cams from Ford will be expensive and second hand cams aren't worth a fart. TB is worthwhile but don't think the ECu will offer any benefits at all. I would think you'd be better off sourcing a 130PS ECU or have your existing one chipped.

Don't forget the inlet manifold is different between the 130 and 105 spec cars
