I have been checking this out myself. you can get your ecu remapped. there are a lot of companies out there doing this. I have been quoted improvement of between 25 to 40 bhp. taking it upto 135 to 150 bhp.... prices quoted have been £250 - £350. this is supposed to be untraceable. other option is plug and go chips..... hope this helps......

quoting a possible re map on a 1.6 TDCi is of no help to the OP at all, as he is talking about a 1.6 petrol......chalk and cheese mate
And as to the fact that a none standard map that has replaced the manufactures map, is not being traceable....that is misleading.....if the map is on the car it's traceable, ie: You turn up at a workshop and they put the new map on for you, and you drive off. Now if you buy a remap along with the kit needed to install it, which allows you to store your original map. Then that allows you to swop between the two maps.
But your still taking a potential massive financial risk if you don't tell your insurance company you have had it remapped. Imagine your in an accident, you kill somebody, your badly injured and taken to hospital, car taken away to be inspected by police engineer ......how are you going to swap the map back prior to inspection by the police ?
Think on, not declaring your re map to your insurance company. Your leaving yourself and your family potentially liable to losing every thing of financial value that you own. And if your a "potless" 21 year old, then you could leave another family destroyed, and on top of that robbed them of the main family wage earner.....could you live with that?
