Hell no, though it's not like the car will go to red line in any gear except balls to the wall in 6th (and there's nowhere, not even the big track at Mosport where the car has enough room to do that)

The ECU pushes the Aslin autobox to bring the revs down as fast as it can in the name of fuel economy and the Steeda tune doesn't alter the shift points unless I want it to (and I'm not mucking with the shift points for love or money)

The numbers do seem low though Daniel ... your car is spec'd by Ford to produce 221 hp @ 6250 rpm and 205 tq @ 4800 (I'm guessing that's at the crank) - it seems a bit extreme to lose more than 50 hp - even for AWD - unless there's some sort of difference in the way the AWD dyno measures these things.

Which tune did you run ... and did you have time to re-flash between pulls?

Yeah, knowing what the car is rated to do on paper, I do suspect the problem is the autobox and how it's programmed to respond to WOT even with the 91 tune I was running.

The shop asked me if I wanted to try a pull with the autobox in the L gear position but I was more than a little hesitant after they reported hearing that "ping" while the car was in D.

I didn't get the chance to try it again with the changes they suggested, but seeing as how the changes they suggested I make would make the tune even safer, it probably will have lopped off a few HP & TQ numbers at the high end.

Using the "butt dyno" though I can safely say that the car does pull much harder than with stock tuning. I stand on it and I get a healthy shove into the seat (and into the lumbar support... ow :ph34r: )
