Installed the GFB DV (what a PAIN!!), the cp-e RMM (also a pain, and I HOPE it does actually 'break-in' some, since I don't mind the vibrations, but it makes a loud buzzing type noise almost like a heat shield rattling at idle rpms), and did the first oil change @ 1200 miles with an FL-400S filter, and Castrol Edge EP 5W-20 (gold bottle).
