Question about 2003 Chevrolet Silverado 1500
Buy gaskets deffinatly. but no, no reprogramming required. However i do suggest a SUPER CHIP, its a piggy back tool that remaps the fuel and air intake for modified trucks to save MPG and/or increase Horsepower and Tourqe. If you are just installing headers, make sure to tighten the bolts going from the middle of the exhaust manifold(headers) outwords, keeping the tourqe the same on each bolt. otherwise you could lose compression and send a piston flying through your block.
