i'm on the fence on what gauges to go with, my performance shop is an AEM dealer but i dunno what kinda deal i can get, but here are some questions regarding both the AEM and PLX devices gauges.
AEM vs PLX Devices Mutli Gauge
1. Which gauge is going to be easier to install
2. Which would yield more accurate readings
3. Whats involves in both installations of either Gauge.

Thanks in advanced!
P.S
They also have some type of OBDII device that you can plug in, and supposedly add devices to your gauges through OBDII using their sensors i'd like some feedback if anyone knows anything about this, otherwise im calling PLX in the morning for some details
