There's talk the 5-oh will get a bump HP, up to around 420-430. Anyone
want to guess where they'll find the increase? With the tailpipe
changes, and due to the fact the '11 & 12's have an extremely quiet
exhaust note, I say it's say to safe the exhaust system will get less
restriction and the computer a re-flash. But I can't think of what
else Ford will do at this point -- a model year from a major redo.
