For a 2000 Silverado? Um no that's a rip off. On the older car's they can help a little bit. Not much but better than nothing. On your truck you'd be wasting your money. Get yourself either a Diablo Predator programmer, or a custom tune by someone such as Charlie Wheatley or www.gowheatley.com or www.nelsonperformance.com

 

I second that, don't waste money on a chip that does next to nothing. Go for the good stuff.
