air/fuel ratio questions
I have been messing with a wideband a/f gauge latley and this may be a dumb question but is there any way to change the a/f ratio at WOT a littlew/o a tune?My a/f ratio if at 15.2 at wot,is this safe or not? i never see the gauge"aem" go in to the green.mod-306 h/c/i

Holy ****, 15.2 at WOT? That's lean... REAL lean. I'd stay off the throttle until you can fix this issue. First things first, what's your full mod list, right down to the fuel pump. Also, are you sure your gauge is accurate and are you sure the wideband is calibrated properly? What's the AFR at idle and under normal driving conditions?

i'm trying to remember back to when we tuned mine. i thinka/f ratio should be between 12.2 to 13 ideally. when we startedtuning minei was sitting at about 14.something.ithink that was running a little lean.can't be for certain my tune/dnyo sheets are in storage. i was thinking about leaving it there for the added hp gains and save on gas. however, wewent with the proper setting.right now, ijust can't be sure about the numbers its been a minute.

Even 14.0 is lean for WOT. However, the desired ratio is going to depend on your mods. The hotter the air, the richer you want the mixture. For example, if you're running forced induction with no intercooler you may want an 11.5. If you have an intercooler you may want a 12.5. I can't think of many situations where you'd want 14.0 at WOT... well unless it's nice and cold outside plus you're running some good gas alonng with methanol injection. Then it may be okay
