Do I need to upgrade by Fuel Spring

Hi All,

I am getting my 2005 6.0 Powerstroke bulletproofed and other items right now.

They are installing a Regulated Return Fuel Kit from Driven Diesel - AKA "Strickly Diesel".

I am reading many post about powerstroke owners upgrading their fuel presure spring with a new stronger blue spring.

Question. Do I still need to upgrade my spring or is this new kit a total replacement ?

Thanks for all your opinions.
