I have a choice between a super chips remap (bluefin), £365, revo £420 or via star performance; £299. Jim at star said to me that the 170Bhp cr is pretty much at its limit and i'd probably have to get a new clutch past the 285Ib of torque. He thinks i'd only get an extra 15-20bhp but i've read loads saying the cr 170bhp can run at 200bhp all day long.
