im looking at getting an air/fuel gauge for my truck and i was wondering if i need the wide band or the narrow band gauge. right now im running stock except intake and exhaust and i have a super chips flashpaq on order. my truck is an 05 1500 4.7L.

thanks in advance

 

Need a wideband

 

awesome thanks for the quick reply

 

Do you need to weld a new fitting on and add a new O2 sensor? Or can you tap the factory wiring/sensor?

 

The factory sensors are narrow bands I believe so no you can't tap into them. You need to buy a new bung for the sensor weld it in after the front O2 but before the cat.

 

Tapping your stock sensor and using a narrow band o2 get you nothing but a worthless blinky light. If you want any useful info you need a wideband.

 

do i need 2 sensors or just one?

 

Just one
