Similar to the chip version where you buy more chips, to tune more cars with the flasher version you have to pay for a new flasher each time. So I suppose depending on the cost of the flasher vs. chips you can choose from there. I'd rather have a flasher so you don't have to worry about chip connectivity issues.
