Ford Fiesta ST V3 Flash Tune Upgrade – Dizzy Tuning

Jason, to confirm, we can upgrade from your V2 to the new V3 flash tune that has some incremental improvements. Do you happen to have access to a dyno plot overlaying the two?

 

[Jason@dizzytuning]

Yes, correct. If you already have my V1 or V2 Flash Tune, then it is a $40 Upgrade fee.
If you do not have my Flash Tune, then any purchase from 12/30/2025 have been getting the new updated version.
I do have a Virtual Dyno graph in the post above, I am working on getting a car on a real dyno.

Would it be possible to have the mods done to the car indicated? Your other post of the Focus ST tunes has this.

This car has a Cobb intercooler and intake. That's it!
