    so how is it you mix and match segments? is it done with EFILive? I have a base tune as well and cant match all the segments.

    You can use EFILive if you can find tunes with all of the segments you need, providing they are all in the same operating system. I was unable to find all of the proper segments, so I sourced the file from someone who is able to flash in the proper file via tech-2 and then read that file back out on a bench.
