which is more important air/fuel gauge or fuel pressure?

 

Fuel pressure mate. Unless you are going to get a proper wide band set up the air/fuel gauges are just disco lights on your dash.

 

id say both like porky says u need a wideband afr as stu said in a post the other day his fuel pump gave up and the afr gauge displayed lean so i guess if u have a fuel presure gauge and a afr wideband u get realy good idea whats goin on

if its wideband then AFR is better, as that covers both really!
