I'm looking to start modding my 2011 WRX, and I'm planning on adding a new TMIC, EBCS, fuel pump, CAI, in addition to the TBE. I'll be going the etune route since I don't have a tuner closer than 4 hours away. My question is, are gauges necessary, or is that more for people self tuning? If so, which ones are recommended (boost, wide band, oil pressure...)? The car is my daily driver and won't be tracked any time soon. Any advise is appreciated. Thanks in advance!
