hello all i took the 5.3 out of 03 avalanche and installed the same year 6.0. everything is all hooked up and running great other then a random PO300 code. I have copied over all the 6.0 tables i could. I used coils from 5.3 and plugs and wires because they where new. also i used the MAF from the 5.3 i will attach the tune in the truck and let me know if anyone can see anything. I have 5.3 swapped a few s10s but this was a plug and play and feedback would be a huge help.
