I have a T43 in a 6l80 2011 behind a 5.3 that I cannot load the stock or modified tune. I get a checksum error at the end. I have seen where other tuners can cause a problem somewhere in the tune. I had a Diablo but sold that thing to get a EFI Live. I am guessing this is the problem since nothing will load but I can pull the tune. I have attached the stock and modified tune if anyone can take a look. Thanks
