4th gear goin rich all the time.

[nathans1987]

do many people have trouble with 4th gear being rich? i tune for wot in 3d on the street and my 1st 2nd and 3rd gears are nearly spot on. logs usually show 1.00** for ben ve afr thingo. but 4th gear goes rich somtimes only after a hard 1st second and 3rd race. it gradually leans out as the rpm rises somtimes. is that stomp compensation? or cat protection? any other ideas?

i posted up my logs the first one you can see it go rich in 4th and the second one it actually goes rich in third i think thats a first. i can actually notice the power loss from it going rich feels like breaking down kind of. is it possible to be plugs?
