dblias in germany will sell you re profiled cams for 200euro and they claim they add 12bhp , you will be supprise by the ammount of power you can get out of this little engine but not worth bothering with unless you find it hard to be insured on anything bigger . superchips claim to remap for £293 +5bhp . when i had my 1.2 engine in i modified the inlet and head , had the cams done and a custom made air filter , it did 92 bhp on a rolling road but it wasnt fast and there wasnt much increase in torque which is what you really need
