That's correct, here is what I was told by Mark Yagelo at Roush:

The ECM is on site. I'm told the Calibration Team is transferring the necessary cal changes from the 427 strategy to the 511 strategy. As soon as this task is complete, the ECM will be flashed and returned to Erick. The strategy is proven in a slightly different application. The actual changes are virtually transparent between the 427IR and the 511IR calibrations. We have high confidence this is going to work perfectly right out of the box. Erick is more than capable of driving the vehicle and giving a competent evaluation of it's performance. If there are issues, which we do not anticipate, we'll deal with them as they arise.

Patrickt, if you recall the engine had a high idle being about 1100RPM and created the grabbing effect you saw in the video, however its now reduced to 950 based on what I was told by Erick Voss of Voss Performance::

I got the ecm and went to Hillbank put it and drove it back to my place, the idle is at 950 so much better then before. I have to do some wiring and drive it some more.

Given that Lance Stander from Hillbank Motors will do a final test drive and provide feedback before I pick up the car from his showroom on December 12th. I believe it will be ok from then on.

And just to put a final cap on this episode the transmission issues were fixed and were described by Mark Bowler as:

This is not a warranty or failure. This is lack of taking the time to set the shift points. I am very confused, I have been doing this 23 years and deal with top builders across the world and have never had anyone not understand that the transmission must be calibrated once the car is running, and I have never had any of them not take care of it them self. As you and I spoke before you shipped the car, it had to be calibrated, your words were you didn't want to worry about that and that would be John's responsibility to handle it, that you were not paid to do that. I disagree, if you are a car builder and your job is to deliver a finished project to the customer, then it is part of the process. I know that probably sounds bad, but I have heard Roush and Bowler thrown under the bus form the beginning of this failure, which ended up being a bolt lose on your end that caused all this commotion. Yet we are still being thrown under the bus.... The only reason I suggested going to Mike at Compushift is due to you not wanting to do this yourself. This is something that anyone can do with a few minutes of driving and tuning. There is no way anyone can calibrate a transmission to shift perfectly without having a completed vehicle. We set the basic calibration with what data we have from the customer and then the rest is in the hands of the builder / owner. Every individual is going to have their own personal settings on how a car should shift and perform. If you do not want to take the time to travel 30 minutes to Compushift and have him tune the shift points for you, I recommend to set the shift points yourself. Trust me I understand the value of time and know where you are coming from. It takes about 15 - 30 minutes to fine to tune the shift points. I have arranged Mike to do this at no charge for John and all you have to do is deliver the car and wait while he sets it up. Mike or I would be more than happy to spend the time with you on the phone if that is more manageable.

I make no judgement value regarding this communication between Mark Bowler and Erick Voss, what happened to my car should never have occurred and speaks for itself. I do believe however what happend was among other things a result of not putting sufficient seat time on the vehicle to shake out these items before it was turned over to me, thus to all newbies who read this post and all enthusiasts who are ready to pull the trigger, may I suggest you consider making sure part of your written agreement is the installer put several hunderd miles on the car before you take delivery just as a precaution so you don't have to go thru what I did.
