Need help with a stock '0411 5.3 Liter / 4L80E .cal / .bin file

[LRT]

5.3 / 4L80 was available in 3/4 ton and one ton vans with short wheelbase and single rear wheels.

Vans didn't start using LSx engines until 2003. These would use a 1Mb computer.

LRT is 100% correct, the vans had l31 style engines through 2002. The 48/4l80 files I have seen are 1mb pcm. Here is the segment swap file.

Is this file still available? Mind posting / sending a copy?

I need to see the secret handshake first.............

I actually discovered gm made a run of 5.3/4l80 light duty 2500's in 99-00, I believe this file to be from one.
