OK, here goes. HP not quite what i was expecting, TQ was pretty massive gain, which correlates with the seat of the pants feel.
EcoBoost vehicles do not operate nor are they even able to recognize AFR. They actually operate on what is called Lambda.

Livernois, am I correct in my belief that you are not one of the tuners at Livernois? Do you know what Lambda is? 14.7 x Lambda = AFR. So, the Ecoboost tunes might use the equivalent Lambda values in the tables, but they are still talking about AFR. 14.7 is the stoichiometric AFR for gasoline. Yes, it is different for alternative fuels and I think Cali 91 octane might even be somewhere around 14.13. A lambda of 1 is stoich.
The dyno's measured AFR from the tailpipe sniffer had to be messed up on that stock baseline. There is no way Ford's calibration would have the motor running that lean at WOT.
You guys should plot your dyno curves vs RPM and not speed.
Interesting about the less than expected horsepower gain.
Livernois advertises 59 HP and 82 Ft. Lbs. peak gains which would put it about 425 HP and 440 Ft lb torque when all is said and done and that makes more sense. When you compare to a Porsche Cayenne GTS (440 HP and 440 Ft lb), the 0-60 times are identical based on the info in this thread--both at about 5.1 seconds. The vehicle weights are not much more than about 100 lbs or so different.
I would tend to believe Livernois' claims.
big difference.
hold brake, press accelerator to 2,000-2,500 let off brake and stomp it. enjoy!!!!
You are welcome! I barely post but I read a lot and I finally got convinced and decided to become part of the Livernois family. I can't wait to have my hands on that V4 tune!!!
