If you are eliminating your air pump and main catalytic converter, then you should also eliminate your ACV (Air Control Valve).

Can you list all of current mods?

 

Hey Jonski, Fancy meeting you here I too am thinking about doing the same thing...is there any drawbacks to leaving the ACV in place when the O2 pump is removed?

The hose job fared well, but not real well...Am still messing with Team Home Depot to see if that's actually what's causing the 11-8-6 boost patter...

 

I don't think anyone knows exactly how the ACV works. Check out pages F-115 to F-123 of the service manual. It explains the ACV. However, I just skimmed it and I couldn't figure it out.
