Thomas,

Doubtful u will find any info. U really will need to ?read? the prom altho the early tuners didn?t make drastic changes to the stock calibration. Maybe some extra timing and little more fuel, fans on sooner,, disable DFCO. Things like that.
What mods does ur friend have?

Only headers and a 4.10 rear axle are installed, rest is stock. Maybe one of you has a kind of datasheet such as Marc has for his calibrations.

I may have a bin I read from a DRM chip many years ago. However, that doesn?t guarantee anything regarding what is in your client?s calibration.

Thomas,
