    Congrats on the great numbers! I know it is only 7 or 8 hp peak gain, but can you feel the difference the tune makes? Peak horsepower doesn't always tell the whole story. :)

    More good news: @ 30K miles the engine probably still isn't "completely broken in" yet and is likely to show improvements in fuel economy and performance at least until 50K miles. Ford engines last a long time even with a bit of abuse.

    On the whole 270hp side thread: if you assume 15% drive line losses for the purpose of estimation (which lots of people do, so at least it is a popular bold guess) then converting from rear wheel hp to hp at the crank is:

    270 * 0.85 = 230 HP at the wheels

    It seems plausible that a 4.0L could do 210 HP at the wheel with the basic bolt ons, a brilliant custom tune, and some luck (one of those factory freaks that just run better than the other cars produced that day).

    210/.85 = 247 hp at the crank

    As far as possible vs. impossible goes. You have to be sure there is enough fuel and air to get there. 250 HP at the crank is a lot to expect from 6 x 19 lb fuel injectors. With 24lb injectors it is hard to say if 270 hp is possible or not at the crank.

    Is the problem that the 270hp claim did not include units of measure and was rounded up from say 265hp at the crank?

    If the claim is for hp at the wheel, it doesn't make sense.

    Ummmm ........ nope. It was broken in at about 10k miles. The only thing that even 'breaks in' is the pattern of wear on the cylinder walls and some of the bearings. That **** is a myth, you dont magically make more power the older a engine gets.
