Do I need other upgrades?
Sinister Diesel Regulated Fuel Return Kit for 99-03 Ford Powerstroke 7.3L w/ Integrated Fuel Filter
I have a hydra tuner and S&B air intake on my 2001 7.3, can I install this fuel kit without any more needed upgrades, and if I do, would I need to get custom tunes made, or could I keep the basic tunes already on my hydra tuner?
