question about removing exhaust air pump??

It doesn't increase power much. But every little bit helps. Yes, it's easy to remove. I think it's only 2 or 3 bolts. You'll have to decide if you want to remove or leave it in place and plug that tube that goes from your exhaust to the passenter side of the motor where all the smog stuff is (vacuum lines, sensors), depending on if you have strict smog laws where you live? Once the pump is removed you can get a shorter belt which is much shorter than the factory belt because there is one less accessory to turn.
The only thing I'm not clear on (anyone??) is once you remove the smog equipment will that constantly trip up codes and make the engine light come on? Is it possible to have all the smog equipment removed and not have the check engine light on? And if the check engine light is on...does that mean that the EEC-IV has gone into safety mode...& my motor isn't running at it's full potential? Sorry to answer a question with a bunch more questions, but since we were on the subject....
