Hey everyone,
I bought this truck two years ago and am awful tired of being the slow one on the block.
I need a tune... Badly. Would anyone be willing to give me some help? Its on a 2013 gmc sierra 1500 with the 5.3l
it is running 35 inch tires and has exhaust work done to it and i installed some 4:10 gears to make up the difference, but other than that its bone stock. would someone be willing to take me on and tune this beast? It would be greatly appreciated. I messed around with it alittle but but its been so long since ive used efi...
Sorry if im in the wrong area.
