EGR delete

Does the ECU need to be reprogramed after removing the egr valve and all the emission control parts?

You'll be just fine without it. But your going to trip your SES light, so unless it doesn't bother you. Your gonna need a retune to get it out of the system. That's all.

the ecu doesn't turn on the SES light most of the time with OB1 cars (93-95), but it will turn on the SES light most of the time with OBDII's(96-97).
