Throwback to an epic classic from my early 20's, long before I was building HDCircuitry LLC wiring kits, to the early forum days and rice rocket era. A compilation vid that Charlie Salas made from '06-'08 when I was just having a blast with the truck, mid-college and working every chance I could to fund a basic build when I just converted the truck from N/A to S/C, and living that early 2000's life of wrenching in driveways, shredding tires at every get together, and hanging out with the DelValLO crew at the track.
