i strongly do NOT recommend the use of regular A/F gauges (non-wideband). The way its installed, it taps off the ecu's a/f signal, causing the ecu to not get a full and accurate reading of the o2 sensor, therefore, outputing the wrong amount of fuel. When you tap the wire, the signal splits. Sometimes, its in negligible amounts, but why the risk especially on a boosted vehicle. The ecu NEEDS accurate a/f readings. I've run many tests and datalogs along with other reputable tuning companies to determine that regular a/f gauges are plain crap, can negatively affect the engine's safety, and does not allow ecu to see accurate a/f.

Monitoring the Datalogger for the factory o2 signal I have seen no changes. The only way the voltage signal will change is with the wire put in as a series circuit.Or a $h!ty install job.You can watch the voltage from the o2, cut the wire and will see no change.
