OK, This might be a really dumb question , but couldnt find it in the forums, and dont know what the proper response is.
So i have a 2004 tahoe that origally came with 5.3 - 4l603 trans
swapped to a drivetrain from a van so now the engine and trans is a 4.8 - 4l80e
using the original ecm i seg swapped the 4.8 and 4l80e.
Im trying to keep the vin so i left it alone, i wrote it entire, and when i went to read it again to double check , the TUNE OVERVIEW still shows its a 5.3 , which is
probably cause thats what vin comes up as, but my question is, is that going to affect anthing? and if so what? will it work like that, or is there a better way to do it?
please let me know what i should do , if you know,
posting both files just incase needed
THANKS IN ADVANCE
