I have just done a 4l80e swap in my 2006 silverado ss... I'm having trouble tuning it. I need a trans tune from a 06 truck with a 4l80 in it to go off of..I am using efi live.. I need help

 

You need to swap the segments, I am sure the efilive forum has info on it. I use HPT so it's different.

 

Post up your tune, and I or someone will do it for you. If you want to do it yourself go to tunefiledepot.com, and download a matching OS that uses a 4l80e. You can't just copy over the tables as there are hidden tables. You will need to do a segment swap to make it work properly.
