Awesome, cheers mate. I'll order a 2nd XSL, and wire up the gauges once the XSL arrives. I will hold off with the IAT as the car is drivable, I'm trying to do as much preparation as I can until I get my forester booked in for a Mafless flex fuel tune.

Thanks Adam for clarification. Is it possible for me to wire in my gauges as mentioned prior to getting my car re-tuned and get my tuner to recalibrate/update the new inputs to the ecu, or is it best to leave the wiring for the tuner?

Hi, I'm Aaron. Fresh noob, and first time posting. I'm currently planning on replacing all my aftermarket gauges (Prosport Boost, Wideband, Oil temp, & Oil pressure) these aren't connected to ECU. I'm going to be installing AEM X Series Boost, Wideband,Oil temp, Oil pressure, and a Innovate Motorsports MTX-D Ethanol content sensor. I currently have 1 XS expansion loom (101-0106) and wondering if I'll need another, and also which pinouts will be required to connect all gauges inputs and outputs. I'll also be adding in a Denso IAT sensor. Also, by adding these inputs/outputs, will they affect my current tune?
