engine help please

[1sik7t2]

so you agree that my o3' pcm won't work with my 05' eng/tranny? the pcm was sold to me by a guy here on this forum who WAS my friend...i think he knew it wouldnt work because he disappeared soon after he sold it to me....so sounds like i need a oem pcm, then have it flashed to my specs, as long as it's a 05' 6.0/4l80e trans?

VATS does need removed and then it should run, the tire size is for the PCM to be able to talk nice to the trans and the other way too. how much are they charging you if ya dont mind be asking?
