Hey guys just joined, I was just curious if anyonecould help me pick out a programmer for my 2003 silverado. It has the 4.8 under the hood basically its between the superchips programmer or one of the hypertech programmers.

 

Pretty much everyone on here is gonna tell you this. Don't get a programmer. Get a custom ECU tune by someone like Wheatley Tuning or Nelson Performance. You'll get much better gains.
