To attempt to clarify your questions though.
1.) The special note of no hard parts required on the $1800 tune is still factual. You are lumping 2 different tunes into one in that statement. Dinan + requires no additional hard parts. Dinan +HE requires the heat exchanger. They are the same price but Dinan + has a lower power output as we found that above that power output the car de-rates itself in order to protect itself. When the Heat Exchanger is included that problem goes away and you can get more power. That said if you get the Dinan+ tune and in the future wish to get more power you can upgrade to the +HE (with heat exchanger) or the Stage 1 at no charge from Dinan (dealer labor charges would still apply). Chances are this requirement will not be needed on the B58 so there will be only 1 Dinan + (warrantied) file vs. the 2 on the S55.
2.) Am I to assume that the Stage 1 (91-93 octane) will lose power when the engine warms? If their is no heat exchanger present on Stage 1 (regardless of octane) than after repeated hard pulls or long spirited driving there is definitely the possibility of the engine de-rating itself as a self preservation tactic and thus reducing power. Again, this is an S55 specific trait and will most liekyl not be applicable to the B58.
3.) If you put lower quality gasoline in the car then 91/93 the car just will produce less power. No other side effects would occur unless you were running and race gas or E85 octane mapping and then put 87 in there. Then you have different issues.
4.) Pricing I won't comment on as I have stated before it has not been discussed for the B58 platform. Applying arguments to unknown variables is a disservice to everyone as it just muddies the waters and creates more speculation.

Thanks for the explanation. I'm not a "rocket surgeon" so I took a stab at what I could based on the S55.
With the "piggy-backs", info was pretty straight forward, "Sport" or Elite (stage 1 .v2 and the .v2). Now, with the flash being a Stage 1 also and then variations within that flash can be confusing.
I'll wait until the B58 Flash is introduced and how it's marketed before deciding to upgrade or stay with what I currently have.
I was exceptionally happy with the Elite .v1. Easy, no nonsense dealer install and if one wants to go back to stock, simply unplug it.
Thanks again.
