When I initially bought my fox the seller had given me a new bumper and a box full of parts. I totally forgot about the parts until now and started looking I found a new aic (needed it). New tps(can't hurt), new throttle position sensor (needed it), new thermostat, radiator hoses, bump steers , water pump, and this has anyone ever seen this chip thing before? Everyone has mixed opinions on chips just wondering what it would do if anything
