I have the old Zeitronix set up, it by far one of the best for the money. The new Zeitronix is the shit, programable LED warnings triggered by the values you set for AFR, boost, ect. simiulated narrow band output, ect. A wideband guage is pretty much worthless for tuning, and for the price of an AEM ugo you could get a Zetronix and somthing to eat.Originally Posted by TRYMY4.0
