hi! required into post. Im new to all this. 25 years of being a mechanic. trying to get my 83 elcamino running. 5.3 out of a 2003 yukon. pretty much stock. drive by cable, th350, osid 12570558 trying to use tuner pro and pcm hammer. already paid someone once to turn vats off and oddly enough its still on. so this is where i learn how to do this so i dont have to pay again for my lack of skill and knowledge. now just trying to get to the next step and get this running for good. thanks in advance!
