Just purchased a 2003 Chevy Silverado LS ECSB with about 94k miles on it. It's 2WD, Automatic, 5.3L Vortec and is custom painted a metallic black with grey cloth interior. No major plans for upgrades, but I would like to improve the fuel economy if possible. It has a K&N CAI and true dual catback exhaust off stock manifolds through flowmaster mufflers. Any suggestions welcome, though I assume the obvious answer is a bed cover. Any recommendations on turners?
