I assume u mean the cut points the state holds out as pass/fail standards???.....The ONLY pass or fail gases are HC/CO.......if ur using the dyno NOX is added into the mix as well....

Most new cars tend to put out low emissions... maybe 10-60 PPM of HC's and .01-.30 % CO..and NOX also tend to be low, below 500 PPM...........but a WRX will never go on the dyno cuz its AWD......so NOX r not measured....
On those cars that can't go on a dyno, we use TSI(two speed idle) testing, and revert back to functional EGR testing if the car is so equipped.
