what do i need to get a afr gauge i mean is all you have to do is get a wideband and gauge. thanks

 

Just make sure its a wideband. I just bought the ngk kit for $240 shipped. Cheap! and the sensors are only $80. Readings- high 14s up to 0psi, mid 12s up to 6 psi, and mid 11s up to 14.5 psi. ( thats if everything else is set right, timing....)

 

There is a group buy on widebands going on here.
