Yea I did the same thing with all 4 of my camaros i pulled the pump, the lines and the little vacuum modual behind the intake, and capped the lid..it will throw a 2nd air pump code because the O2s see no additional fresh air at startup..you will need to get it base tuned. after that no worries!...Have fun it makes the engine bay so much cleaner

Nah its your primary O2s that read the extra air coming in..all that pump does is help ignite the fuel in the exhaust from cold startup to heat up the cats(pointless since u have no cats) when your at operating temp(closed loop) it wont turn on again till the engine is cold and your starting the car
