Hello all. New to this forum came over from Tech. Used to have a 98 TA, now im finally back to the LS platform with a 03 Silverado ECSB Z71. I love the truck. I am going to do fluids, seafoam then plugs and wires. Then it's mod time, I have been searching for a link to a e-fans writeup but no luck yet. Anyone have a good source? After the fans and tune up it will be tune time and maybe a cutout. Looking forward to learning about the 5.3!
