Its a street car, turbo 5.3, hopefully on E85. I just got my 5.3 yesterday and the knock sensor harness is doofed up. First question, do most people run the knock sensors? The engine is from an 04' Tahoe, will the harness and sensors below work? Also, if I Megasquirt the vehicle, would I then want a Knocksense?
