need a copy of original tune 8594 os

[tokymon]

hello have a customer who's truck was tuned by another tuner
when i read this out it gives me checksum errors
os#12628594
cal#12628778
diag#12628779

both the cal and diag are with a red x in front of them so i imagine that is the bad checksums

anybody with a stock file for this would be gratly appeciated
