    Need base tune for gen 3 DBC 4.8l ls

    I was given the wrong ECU and instead of a 4.8 tune file, it was 5.3. My motor is a 4.8l gen 3 ls with DBC and a maf, instead of getting another ecu id rather just change the tune file so if anyone has the base tune file for the specs i mentioned it would be greatly appriciated.

    The tune repository probably has a stock file to cover it.

    Can't find the tune repository or can't find the file you are looking for?

    What is the year/make/model of the vehicle the 4.8 came out of?

    There's at least 5 different files in the repository. 2000, 2001, 2002, 2003.

    I am fairly certain I have a stock 2004 or 2005 DBC 4.8L as well.
