Side effects of an inferior tune result in improper timing, unburned fuel and contaminants that enter the exhaust stream and break down key internal parts of the catalytic converter from excessive heat and corrosion. At this point, the converter not only loses its effectiveness, it also becomes very restrictive to exhaust flow, which kills horsepower.
