is 245 hp for real

Dear jayray--  I surely can't answer that question off the top of my head, but I did find a knowledgable source online who can.  It looks like you might add up to 100 hp, with the Powerdyne #6 boost, making an already top performer into an all-star.  To read Mike Troyer's estimate, go to--http://www.f150online.com/forums/archive/index.php/t-44155.html.  But be careful and don't drive too fast.   Good luck from Bovan.
