Should I update from v.7r50d to 9r07b?

U7146, V.7R50D, 2001 Ford Bullitt
My question is should i update my tool to 9r07b? Will i see any benefits from the update? My car is stock with the exception of a K&N air filter, not a CAI. I"m currently running the performance tune and i do not feel the difference in the way the car performs. It appears to run the same. I verified that the last tune written is the Diablo performance tune.

are you running 91-93 octane fuel?

[Bullitt2294]

Yes I'm running 93 here in Illinois.

[mikel]

yes, the tunes are markedly better.

[Bullitt2294]

Thank you! I will update you guys as soon a buy a data cable.

[Bullitt2294]

Its in and i truly feel the difference on this stock Bullitt. I had a hell of a time trying to get the computer and tuner to communicate. I used the driver that came with it. Cable Unlimited that i picked up from Tiger Direct, is the same driver Diablo has. Anyway its done and it works!!!!! PL-2303HXD_Vista_Driver_Installer.exe
