Need Advice On Fueling I am going to order 42 lb injectors for my supercharged 2000 gmc sierra 5.3. My question is do I need to keep the fmu or will a custom tune take care of the fueling for me? Also, does anyone know the horsepower limits on the stock fuel pump, MAF. Any info will help me please reply.
