I had a great deal on buying my 2015 Silverado LT. It’s not what I wanted (V8, leather, 4WD, etc,) but I’m going to make it work! It’s a beautiful color and I added some black 20” rims and also painted the bowtie black. I have a few more mods I want to do with the lights and adding a backup camera, BUT what I want most is HP!!! I called the local speed shop and they told me there’s really nothing out there for the 4.3L and I wouldn’t be able to notice the small increase with a Cold Air Intke, Exhausts or programming..... Is this true? I mean a few extra (10-15) for each of those mods seems like it would add up? Can anyone give me some advice to get more HP without dropping the obvious V8 I’d love to have to begin with..... Thanks so much in advance! TomBrady80
