Really happy with the results from the 034 Motorsports tune.
The process for flashing the Engine and Gearbox was really straightforward. Got an email link from 034 to set up the account (you'll need to request a password reset). I used the app on my mobile but the PC software looks really easy to use too. Within 20 minutes both the ECU and Gearbox flashes were complete.
My T-Roc R feels like a completely different car. Although the performance is now so much better, the gearbox is probably the best part. The low-speed hesitancy is completely gone, gears engage much quicker and smoother than before.
It's a hoot to stick it in R mode and listen to the pops and bangs on overrun. And it goes like stink too!
