Thanks in advance for the information. I'm new to the forum and new to the platform. I bought a 2016 advertised as the Roush 670 package from an out of state dealer and had it delivered from TX to CO. Spent some time digging into it this weekend and I think I have the additional 727 parts?

I found the unmarked BAP in the trunk with the JMS tag at the harness under the rear seat. I tried to remove the pulley to check the size but I got stuck getting it off (do I just pull the front circle cap off; and after that do I need the pulley remover?) I can see most of the stamped label on the back and I've put together 1313-??80-AA which looks to be the pulley in the phase 1 to 2 kit videos (1313-6K80-AA). I didn't see any ID marks on the idler pulley and I'm assuming it's stock? I haven't checked the plugs yet and I plan to call Roush tomorrow and see what tune they have on the car.

Is there anything else I should be looking into and checking? I'm happy if I have the upgrade but I'd obviously like to know what I have and ensure it's all working. I assume the only other consideration is a better tune from one of the big 3? Thanks again!

Phase 2 since it has the BAP! You can also measure the pulley and see if it’s 80mm.
