Does anyone have a bin for a 6.0 with a 4l80e my original bin is not a 4l80e or a. 6.0 if you have a custom bin with a 3 bar map that be awesome car has a summit stage 3 turbo cam, -12cc dish forged pistons, 823 heads,LS3 intake, I have not bought injectors yet open to suggestions, 3.70 gear, 28 tall tires plan on using E85 going in a 72 Buick GS. I'm debating on buying a hp tuner but I still like to flash with a 6.0 tune first. I do have ls driod and protuner. Already flashed the original tune back on the pcm so I'm ready lol. Any suggestions be helpful.
