The tune file you posted is for a 2007 Yukon XL with s 6.2.

The thread is for a 2008 GMC 1500 with what I assume would be a 5.3. So what is correct and what isn't here?

[Sickandtired912]

So we replaced ecm e38 ecm out of a 6.2 I may of uploaded wrong file

[Sickandtired912]

This is the files I have they removed VATS and used this ECM shouldn?t it rewrite all files I can go hook back to it and relog it if needed

[Sickandtired912]

Can you please help I’m not sure what other files you need

[Sickandtired912]

The computer came out of different vehicle and I don’t have the original log file as an another mechanic done it for me .

If the AFM system is gone and you replace the camshaft, all 16 lifters and pushrods, have all the codes for the AFM system disabled, it should be firing the same on all 8 cylinders

I don't have a stock 2008 truck file to compare with, so I don't know how much of the tune is wrong. Being that it's a 2007 6.2 computer that wasn't programmed to your VIN in the 2008 truck, I don't know if something like that could be a cause of problems.
