It's not a boosted engine problem. The NA 5.0 Coyote in my Mustang loses ~15hp on regular fuel. Or to put it differently it gains 15hp on premium fuel. The ECU's adjust the engine based on what you're feeding it.

$1,000 off invoice or
$1,300 off invoice (if you have xplan) or
$2,000 off invoice (October reservations)
The $1,300 deal will always be $300 less than the $1,000 deal.

If you get a new reservation at Granger in...
Be careful comparing apples to oranges. The Focus automatic was the industry's first attempt at a low-end dual clutch transmission and it was bad. It has zero in common with the Ford ten speed auto.
I'm in Omaha and reservation is with Baxter West. Waiting for B&P to go live then call them and push on price. If they won't match Granger it's an easy decision and a two hour drive.
I won't touch Woodhouse. Too many bad experiences with them. (Your mileage may vary.)
