As far as the tune goes, how exactly does that work? What's to say that the factory didn't get the best parameters for a fuel ratio combine both the best performance and economy? Is there something these hand-held computers know that the GM factory doesn't?
I'm just curious, because I would like to do a tune as well, but this question seems to plague me.
