but it's a tune written by sct, i'll stick to my brenspeed tunes. While brenspeed or b a m a c h i p s isn't a dyno tune, it's probably a step above the sct tunes. According to the quote below, you'd have to erase your 9415 to convert it to a 9400, if you wanted to load someone elses tune like VMP or brenspeed.

"The difference in the SF9415, and the normal 9400, is the preloaded tunes. The SF9415, is preloaded for several vehicles, mine included 7.3PSD, 6.0PSD, 150, and Mustang...it was a 9415B. There is also a 9415A, which includes the focus, and Lightning. It inlcluded three tunes for my 06 6.0PSD...Tow, Street, and Performance. It gave me the options for shiftpoints, Tire size, Shift firmness, and a few other things. To get a custom tune from a Dealer, you must convert it to a 9400. Once you do that, it is blank, and has none of the above, and cannot be taken back to a 9415. If you are wanting to tune very specific things you want a 9400, a Dealer can write you a tune, and use the LL3 file type and LiveLoad to give you the exact on the device options you desire. That is just what I have learned so far...hope it helps..."[/align]

A custom tune makes very little difference on a non modded Mustang!! 3hp if you are lucky!
