I recently got my 2018 Challenger Hellcat. I want to change out the supercharger pulley with the Hellraiser 2.72". I believe I will need to upgrade the fuel injectors. I will be doing the work myself and take it somewhere to get tuned afterwards. My questions are which fuel injectors would be best. Do I need to change the stock fuel pump with a double fuel pump. I am new to this so don't be brutal if I have something wrong. I appreciate any advice given.
