I'm new to GM tuning so bear with me. I did search.
With a lot of E38 factory calibrations, the VE table is not populated.
People say to do the best MAF tune you should have a good accurate MAFless tune in there for when it uses MAFless mode under some situations (transient throttle etc). I assume this involves tuning the VE table.
How does this work from factory when a lot of E38s don't even have the VE table populated?
Cheers
