Because a chip wont do much at all on a standard car. You wont see a huge gain in power. Its best to start off with air filter and exhaust system. Then think about a chip.
A chip doesnt make any extra noise either
But if you interested the main one i can think of is Superchips Link
I have a powerflow catback fitted and a k&n cold air induction kit on order .
I've tried superchips but they don't do one for the 1.4 model.
I know there is a 1.4 sport model with 94 torque instead of my 89 and was thinking of trying to get honda to fit a sport model chip as I assume that is the reason for extra performance on the sport model.
