I have an 04 black 1500 silverado with black KMC backseat rims and a undercover tonnue to save weight and gas. I installed a K&N cold air intake, flowmaster 50 series muffler, and a FMS dyno tune and it puts 264HP to the ground, not sure how much at the engine but my guess would be between 235 to 245bhp, not bad for a first time tuner. I'm currently in the process of installing a Xenon body kit and want to install a fiberglass hood with functional ram air (truck needs to shed some weight. I would like to know if there are any other 03 or 04 trucks out there and what have you done to yours, also looking for other good cheap mods for my truck.
