2015 base file cant get quite combination i need

[shane]

Hi Guys,
I'm tuning a 2015 Z71 and before I start want to ensure that the base file is 100% correct.
the trucks details are as follows.Description Value
Engine Control Module (ECM $7E0)
Description E86B LML Duramax 2015+ ECM
VIN 1GC1KWE84FF123456
Serial Number 864406700770
BCC ABY3
Security Seed $6391
Calibration ID 12661877
HDW Number 12651928

Boot Software 12657305
Main Operating System 12660477 ($5DB2D68D)
Engine 12661878 ($D107D7F1)
Speedometer 12653966 ($95ED9B15)
System 12661754 ($DFAA6AB8)
Fuel System 12653951 ($FBD86B82)
Engine Diagnostic 12663186 ($D3B3B780)
Engine Operation 12661739 ($A5598B02)
I have all the 2015 base tunes and the one that's supposed to be for this model 2500 4 door Z71
it has all the segments identical except the fuel system it is 12653952 instead of 12653951.
will this work or will I need to get a tune file built to match my numbers exactly??
Happy to pay for it just curious if the newer?higher number segment is that different?
I was burnt on the last truck I did by the supplied tune not being correct from a supplier first time then having stabiltrack issues.
the supplier sent me a correct tune but the problem remained until I put the EXACT original tune in , then flashed the 4094 tune back in .
do not want to go through the drama again so want to ensure I have a correct base file to fall back on .

thanks

Go to ridgerunner diesel and buy a stock file from Tony, it's $50. Almost not even worth bothering to ask anymore.
