Installing and testing xHP Transmission Flash Tune in my BMW F31 320d.

I had xHP in my 6 speed automatic BMW E61 5 series. It absolutely transformed that car! A brilliant mod!!!
Let's see how it goes in the 8 speed F31.
It's a diesel, so very torquey and you'll see how it responds to a transmission tune.
Stage 1 engine tune coming soon...
