WHat should I be at?? just curious my aeroforce gauge is sitting at 9.6 and thats with a sct tune for 93 octance, long tube headers hi flow cats and non foulers on the o2 sensors, I thought it was supposed to be higher and just wondering if the nonfoulers are causing it to lean out, the gauge is not a wideband it just reads the obd port so its what the computer thinks it is. thanks

You are WAYYYY too rich.Perfect stoich is 14.7:1. I try to keep mine 12.5-12.7 @ WOT.Mine is a Innovative wideband gauge though.

it runs fine do you think it is because of the non foulers moving the sensors out of the exhast stream???

they are a spacer for spark plugs in bad cylinders to pull them out of the cylinder a bit, I have a couple on each rear o2 sensor, they pull them out of the exhuast so the truck doesnt lean the crap out of it or throw cat low efficiency codes
