Performance EFI chips for stock Arctic Cat models. Changing your EFI chip can both lean down fuel flow and alter ignition timing at select RPM ranges. The result is not only increased horsepower but also very respectable response and acceleration gains. It is very important to use the exact chip for your model including the same color code as on your ECU box and injectors. Engine damage may result by using the incorrect chip
