A chick from work, bought one of those 'power chips', "gain 20 hp" chips off ebay and chucked it on.. Not only did it do nothing but she fudged up her wiring gettin it on, and now her electrics are all over the place.. Wipers go on when they want, indicators only come on when they want to etc... All you can do is laugh... BTW she drives a R34, 4 door, auto, non turbo skyline, so she deserved it LOL
