If you have actually O2 sensors aft the the converters and also remove the converters it will certainly throw a code and WILL adjust the fuel wait mixture. I have a 96 Z71 and also had eliminated the converters the did throw a code but in addition to throwing a code it additionally screwed up mine fuel economy. Once I removed my converts my truck started to gain terrrible gas milage 10mpgcity/12mpghwy. I mounted two simulators native SUMMIT ($88.00pair) and also now I acquire 14mpg/19mpg. It renders a differance if the O2 sensors room in the rear of the converts!
