    454 0411 swap

    Anyone have a base tune for a l29 4l80e? I have done the wiring swap, it runs but runs like crap. Feels like it has misfires and bank1 fuel trims are completely maxed out. I feel it is my tune looking for a comparison, i feel i am missing something. Will post tune as soon as I get home.
