Do you have any particular issues you are trying to solve?

well something doesnt feel right the way shes running, ill know more as soon as i can do some wot logging. but does this stuff i have posted look normal to you?

Your running lean based on the long term fuel trims... ie: above 128, perhaps an exhaust leak of some sort?

Sorry, can't really help other then that..

i know there is a slight exhaust leak in the intermedeiate pipe, but i just put my headers on 2 weeks ago and so far so good. my 02 sensors mv are jumping up and down like crazy between those numbers, anyone have any helpful links so i can learn more about all this? thanks......
