short fuel trim

Does anybody have an idea what the hell this could b.My mechanic says for sure no vac leaks,its not the o2 sensor replaced 3x need help before anything happens running so lean...
 


The code thats showing is p1133 and the fuel trim is maxing out at cruise O2 sensor was replaced 3 times maf sensor is ok checked it with it pluged and unpluged so basicly at idle its good at exceleration its good only at cruise everything goes to hell...

plugged, unplugged, acceleration


Curious... on my HPTuners when I run a scan for the VE can I go by those LTFTs to see whether I have a leak?
