ECM/TCM rollback confusion....

[Sesco4]

Ok so I'm on the list for a remote programmer. I placed an order to have my ficm reprogramed and my ECM/TCM rolled back. Here are my current strategies VXCF9N4 TQCI1NA. According to the PHP website this is one of the strategies that need to be rolled back. So here's where I get confused I plan on running custom tunes and two different tuners that I talked to said that they would wright my tunes off of fords most recent strategy. They then told me that I have the most recent strategy and that it is Fords best to date. So could someone please shed a little light on this for me.

Thanks
