and what does that mean for your roadworthy check if the obd2 emissions fails?

The WMI is automatic. At 4 psi, it starts to spray. It doesn't use much. After a full tank of gas, I used less than 1/2" of the mixture in the tank. I bet the WMI tank would last 6-8 tanks of gas, depending on how often you're at high boost.
OBD2 emissions are unaffected. What I meant was you can't tune out the secondary O2 sensors if you are running catless. You will either have a CEL, or the test will return "not ready". Either one is an emissions failure. The only way to pass OBD2 readiness with catless headers is with relocated O2 sensors and aftermarket cats. With stock cats, there is no issue (other than leaving a lot of power/sound on the table).
