When I had my 2.3, I removed the smog pump and to honest didn't feel a whole lot of difference. I have also heard something to the effect that it can effect valves(exhaust?) and be detrimental to your engine. I ran mine like that until I swamped the whole darn rig.... <img src="/forums/images/graemlins/evil.gif" alt="" />

Good luck!
