Another thing to add, ive used AEM Wideband (Loved it), and have had countless Autometer gauges and have not one bad thing to say about them, there absolutely the standard when it comes to gauges.
Also had 2 cheap ProSport gauges at one point and time and didn't have any problems with them, but ive read a LOT about other people having problems with there gauges, senders, all of it.
