yeah I didn't switch it. I reset the ecu and am just waiting to see if it comes back. I did a quick look under the hood when I got home and didn't see anything and I tried pushing on any hoses that I could think of that I might have touched.
Would the TMIC cause it to run lean? I don't recall ever seeing anything that would make me think it would. I know cobb says that if you use one just to watch for boost spikes and egt's, but nothing about A/F
