  Rob W. asked:

  Any tuners in Minneapolis area that can take a look at my tune? I think I'm running rich and would like to have someone take a comprehensive look. My concern is that my engine, though well done and quite clean, is in a car that looks pretty roached. Not sure I'll get the service I want at a shop full of sparkly nice 500hp Subarus. There's a guy up in Elk River that I contacted but haven't heard back from him. Looking for options, thanks.

  You could call Jim@TPiS T.P.I. Specialties Inc. (T.P.I.S.) (952)-448-6021 Or you could attend the AMP EFI training seminar we are holding at TPiS in April and learn how to tune it yourself so you don't have to rely upon someone else to do it for you ;) https://www.diyautotune.com/eficlinic/

  Joe H. asked:

  Can someone refer me to a place in the metro area that has Oxygen Sensor Bungs in stock? Autozone & Napa have no idea what I'm talking about. I believe GM uses an 18mm size, am I correct? Not sure if I should ask for a straight or stepped one. I bought a new sensor from rockauto anyways.....
