I have HP Tuners( non pro version) and i just got my wideband 02 sensor installed. Currently it is in the rear o2 slot on my speed daddy headers. I don't have the cat installed so i think that location will work. I have the 5v signal from my wideband hooked to to the middle (brown wire) on my EGR plug.That will allow me to log the data in HP Tuners. I do not have my EGR deleted. Can i just leave the EGR plug unplugged from the EGR while i am logging data with HP tuners? Also do i need to tune out my rear o2 sensor and or my EGR? I have searched the forms but what i have found i was not 100% sure of so im asking here!
