My car is in sig. Its a M6 car I plan on very soon installing a 224R cam into it. I have racetronix 39lb. injectors to go with that. It is stock tb stock ls6 intake manifold. I already have a 100 dry shot installed. My question is is it necessary to ugrade my stock fuel pump or just precautionary. Thanks for any input
