You can tap your boost gauge into the hose going into the Bov. I bought some parts from home depot to make a t fitting. The hose off the bov is 1/4 and the hose to the boost gauge is 1/8. look in the plumbing section at the brass fittings.

A/F I think is normally tapped into the 02 sensor. It should come with some instructions. I have never installed one(I think they are worthless for anything other than a light show, unless it is wideband.) Someone else would be better off helping you on that one.

yes.. hes right on the BOV for the boostgauge

as for the A/F connect it to the ecu

I have a A/F gauge and its pretty worthless unless you have a wideband o2.

I thought I saw talk somewhere about the AF meters voiding warranty. I am going to try & find that thread.

Everything "voids" your warranty....You either choose to care or you dont. Remember it is up to them to show that your mod caused whatever damage you are trying to get them to cover...
