My car is far from a smooth drive. I have been in other cars with my engine (Cav GSI) which have superchips, and the ride is far smoother. I know that superchips do not necassarily give a performance increase, but do they guarantee a smoother drive? Has anyone noticed this after getting a superchip? Before anyone recommends the unichip please bear in mind I am only after a smoother ride, and not too interested in bhp increase.
