Re: Any feel like having a tuning discussion?
I would assume that the expert engineers at GM would have already programmed the vehicle to perform optimally - i.e. the best combination of power/fuel efficiency/emissions, etc. I see programming devices advertised for sale to the conusmer and I wonder, why would an amateur playing around with these settings be able to do a better job than an entire professional team? Please don't misunderstand me - I don't mean to be disrespectful, I'm just trying to understand what the goal of reprogramming is. Can anyone please clareify this?
