I have an SCT Livewire 9625OR I bought new a couple years ago. The firmware is 6.4. 058.0 and the newest tune is 64 1.3.4. Is there any reason for me to update any of this. I have been using Mike w/ KEM custom 125 tune and been pretty happy. The only problem w/ the canned tunes is the firm shift is not firm at all and the stock shifting is good but locks up at around 40mph. Would it benefit me at all to update. Please let me know before I go through the trouble of putting back to stock and such. Thank you

I updated it, and I also got the flash done at Ford to the new P30.

I noticed after I did this you now have a extra tune... Tow, Street, Performance, Extreme. They added a Street tune. It also seems like some changes with the Tranny tunes as well.

If you are using custom tunes then you don't really need to, but, you might want to update it just to check out the preloaded tunes, they are really good for preloads
