Mods are in sig...3" Pulley and NGK BKR7E plugs gapped at .035...

 

what do you guys think...i thought i was running really lean for some reason...i guess im just overly cautious, or worried lol but it seems like it still close to the factory A/F ratio...

 

Is the factory in red and the modded one in blue ?

 

I have no idea, i only took the car in with the mods, no stock A/F ratio is on there, idk which one is the A/f ratio it is says the one in red, the sheet is kind of confusing

 

The bottom line looks ok to me, but the top line does not look good. I guess it would be worthwhile to figure out which is your current a/f.

 

You want a 12.3 to 12.5 AFR to be at good power levels and reasonably safe richness.

 

I'll agree with the 12.3 to a point. But I know me running that much boost I'd rather be in the high 11's no more than 12.1 if possible.

 

I agree. I will try to be in the 11's when I am pullied.

 

that looks to lean. Iknow that for the srt-4's 11.7 is safe

 

but i mean think about it, wouldnt i throw a lean code if it was running lean???, The A/F ratio levels out then drops down around 12 and drops some more pretty quick

 

The lower the number the richer, the higher the number the leaner! Good info though! 14.7:1 is ideal for ideling and regular driving. In boost, 12-13:1 is ideal. Throw advanced or retarded timing in there, and it's another ballgame!

 

I really don't think that is correct. I've seen a few 3" pulley dynos with more modds then you have and I think the leanest I've seen was 13.1 at 6k rpms.
