Actually, your post is BS.
When it comes to comparing times, if you aren't comparing them at the same track, on the same night........... about all they are good for is a guideline. Also, every driver is different............ and as many who have driven this car at the track say, it runs completely different than any other Mustang they have ever driven. Thus, there is a learning curve.
To expect the very best times available the second a completely redesigned new car comes out, is assinine.
Case in point on times. I can go to Firebird with my Lightning, and run a 14.0............. as Firebird sucks (everyone knows how poor the track prep is there). I can take my very same truck, on the very same night, to Speedworld........... which is about 40 miles away. With the very same conditions (within a degree or two), I can run a 13.5.
Now, did my truck get mysteriously more powerful while I drove those 40 miles to Speedworld??? Of course not. Did I drive it better at Speedworld??? Of course not, its an automatic. The single difference is the track.
The good 60' times show that the cars launch very strong. However, as some are finding out, the key to decent times is the shift point. Again............. this is learning curve.
Some of you must be very young. You probably also believe that every dyno will read the same.
