Please help! I have a Wahoo speed sensor and cadence sensor on a Tacx booster, using setting 2 as told by Zwift. Everything was fine and I was averaging 310 watts but about a week ago all hell broke loose and I started hitting 800, 900 watts with no real effort! Don’t get me wrong, if I’ve improved my fitness that much I’ll be well chuffed, but I think something has gone wrong 
Any ideas please?
