I want to swap a gm 411 ecu on a Tuned Port injection system. I have 2 ways to do it. I can flash it with a 5.3 os or a 01 G-van. It depends on if I go with coil on plug or not. I also have 2 early 8.1 engines to swap and 2 eary 5.3 engines to swap into earlier trucks. If I get the 6 credit 99-07 year/model package, will thie cover all my engines? I don't know what they came out of. And the hydrid TPI programing isn't in a catagory. I can't find any info on how you license swapped stuff. If I missed it some were please piont it out. Thanks
