So I am going to swap a built 5.3 into my 1997 extended cab and Would like to swap the P0411 as well. I know this has been done plenty of times but what I find everywhere is leaving the black box installed and piggy backing a P0411 ecm to run the LS engine while the Blackbox runs the truck side of things. I understand you could put a van tune on the p0411 to run the truck side but could you modify a van tune to run a LS engine? I have HP tuners for my fbody already and have some experience using it. Ide like to make the complete swap as clean as possible and if I could have just the one ecm mounted in the stock location that would be great. Anyone done this already? Thanks
