Hello to all.
I am new to this forum and EFILive tuning.
I have a 1999 Chevy Silverado that was manufactured in Canada.
When I compare the High/Low Spark octane table from one that was manufatured in USA, the one from USA has a little more aggressive timing down in the lowend.
Why is that?
Both operting systems are OS:09373372
Both Engines: 5.3L
My built in Canada Truck:
USA Truck:
Thanks
