Why am I running so lean??? I have a 98 SS A4 with the NOS 5177 125 shot. I have the stock ends and the stock MAF without the screen. My O2's are in the .850-.870 range with my MAFT set to 14% rich on WOT. On 100 octane I don't have any KR, but on the street I run 93 octane. I haven't a-tapped on the street yet so I don't know if I am getting any KR or not. I would much rather be safe than sorry and get my O2's up into the .920 or so range. Any ideas on what's going on and what I can do to fix it?
Thanks!
Thanks!

Re: Why am I running so lean??? Ok first things first ! <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />
U need to set WOT back to 0 ! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
Now set BASE to 1 ! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
Drive for 50 miles and then ATAP ! <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Then let me know how your readings are ! <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Re: Why am I running so lean??? wow? setting my base at 1 will add more fuel then WOT at 14% rich? I guess I need to learn more about my MAFT <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
Thanks, I'll give it a try.
