Sirloin Tip Roast on BGE with Jeffs Rub Cooking suggestions

I bought a 7# sirloin tip roast at Sams club and have it sitting on my counter. I rubbed it with Jeffs secret seasoning, Kosher salt and oilve oil. I want to cook the center at medium rare. What temp would you keep the BGE at and when would you pull and wrap in foil? Also about how long would it take?

Thanks Guys!
