id get a wideband o2 sensor and gauge if i were to just run nitrous on a mail-order tune.
hell id get one anyways, nitrous is very tempermental, and any change in the outside atmosphere can drasitcally change the way it reacts, whats rich one day could become lean another if the outside air gets to dense(cold). or if its too hot you might get alot of predetonation. too many variables to not want to know exactly what the results of spraying were in realtime.
