Gone into this in some depth on mine. The best performance gains on the Lux come from restoration & attention to detail using the dyno for reference. First thing is to do a power run to see where you are now. It doesn't have to cost a fortune. If everything else is working right. Iginition, Fuel system etc. When I first got mine it made just 112 at the wheels. Pretty average for these. With better fueling & new rotor arm, cap & plug leads. It made 140. Next a head overhaul now 150. Only now would I consider chiping it. JM garage do a good chip. Good improvement in mid range. Usually very little top end. Cost £200. For another £100 you can have a full remap. (Wayne at chip wizards can remap your original chip.) Which takes account of your current exhaust & engine condition & will always be better. You can sometimes get a bargain from ebay for less than £100 that may be worth a try but without testing on the dyno your shooting in the dark. Few people bother to sort the lux. Shame as it's much under rated. Too many knocking about with as little as 90 at the wheels give the good ones a bad name.
