Ok so I want to make everthing easier on my car. So what all can I remove from its that is needed for emissions but not needed to run? Or what can I remove that will free up some power? Oh and I want to shoot big flames!

I remove my ACV, the Air pump, and the cats. Thats the easy stuff. If you want to get whacky, you can remove the vac spider, but thats BIG time work.

Idle control is not junk...

The only thing thing the will free up power when removed is the cat. There are no gains from removing anything else, it just tidies things up a bit.

Once the cat is gone the ACV and air pump are redundant anyway, so you might as well remove them. You need a block-off plate and some rubber vac caps for the ACV. You shouls also get a double-belt pulley for the alternator to make up for the lost belt.

Removing the vacuum spider and solenoids isn't hard, but it pays to know exactly what you're doing before you start.

RED = vac lines

It is to me. It's not needed in my application, so all it is doing is taking up space.
