Hi all!
I've been driving a Golf R 7.5 Special Edition for the past few months and recently tuned it with Galano Stage 1 ECU and Stage 3 TVS TCU (I switched from Galano TCU only as I preferred TVS from my previous Golf). The car is completely stock otherwise.
Since tuning, I’ve been encountering a strange issue: during a pull, it starts off strong, but about 1 out of 3 times, I randomly lose torque. If I back off the accelerator and press it again, the car responds normally. There are no logged faults in any modules, and no warning lights on the dash.
I've been trying to troubleshoot this with my mechanic, but it's tricky since it’s not consistent. This weekend, I did some datalogs with the OBDEleven app (which can be a bit of a hassle), and finally captured the issue.
In the datalog, you can see a few normal pulls, but on the last one, the torque drops by almost half (confirmed by the butt dyno).

Any ideas?
