Hey Bro,
Sorry for late reply. Here is the breakdown:
-APR HPFP: This is a pretty good mad addition. pulling hard thru the rev range this sucker ensure that enough fuel is carried and channeled thru consistently and as a mate said "Its fu*kin bulletproof". *4 star
-Good Ridge line: Ensures consistent good bite due to the reinforced steel braids vs stock lines that expand considerably under hard braking and excessive heating. *4.5 star
-Forge DV: I personally felt was a waste of time. went back to stock because it wasnt holding boost well even though i changed spring rates. *2 star
hope that helps
