ok so by the looks of it there are 8 updates for my car?

wow... 10 updates

 

I don't get it? What's the point?

 

its just little tweaks that gm does to the ecm, to help improve the cars performance, mpg, idle, and other systems. like for instance when i turn my ac on the car almost dies and has died in the past. i can go to the dealer with those cvn part numbers so they can install them

 

They just flash that ****?.. For free?

 

a good dealer will do it for free or little to nothing... the dealer i quit going to wanted $90/hr to do it. with a 1.5 hr mininum. if you got a friend or a hookup at the dealer its free

Keep in mind that sometimes the calibrations can change the way the car operates and you may not like it.

 

yeah thats why im kind of scared to have it done... im getting a tune soon so would it matter if i have all this done first? i know the ac idle SUCKS
