New Zwiftie here. I linked my Tacx Flux 2 to Zwift and my head unit just for me to easily follow my data. However, Zwift is showing consistently lower power than my Garmin when connected to the same unit (Tacx Flux 2). I have calibrated the trainer before each ride, both are 3 sec power averages but they never match. Only concerned since Zwift is showing consistently lower powers (20-40 watts) compared to my Garmin. Theoretically they should be displaying the same numbers if they are both connected to the same power source (Tacx). Please help if anyone knows any possible solutions!
