Well this is odd. A/F ?

Well i got an aif fuel gauge over the weekend and hooked it up accordingly. i searched through the posts for installing it and im pretty sure i did it right. i went off the front o2 sensor. if i understand correctly i should ignore what it says during regular driving and concentrate on wot correct?
Anyways my real problem came up during a couple of runs at the track. With nitrous (45shot) i was running stoich with 2 bars lean. But when i did a couple runs WITHOUT the nitrous i was running mostly lean 2 bars into stoich :wtf: This is on a stock pump, plugs gapped at 35, on 93 octane.
So now what?

What do your plugs look like? If your plugs are really lean looking I would be concerned and start checking things. Start with the Fuel filter then the Fuel pump. You should also get a fuel pressure gauge to make sure you are getting the correct FP.

time for a new fuel pump i guess.

Since you're spraying I would suggest getting a Walbro 190 lph or Walbro 255 lph Highpressure Pump. I have the 255, but no air mods yet, so I would assume that the 190lph would suffice as I run rich since I don't have any breathing mods.
