Problem with cars horsepower

Since the last update, my cars are only acheiving about 50% of the horsepower that they should (when in menus, hp would be like 252 but during the race it only go up to 126 ( was driving stock Lotus 2- eleven). This also happens to any other car and I don’t have a mod decreasing power. I cannot win any race since I’m being passed by everyone. Is this commun?

Turn on your telemetry and see what throttle settings are being sent to the car. Maybe your controller or throttle sensor(if using a wheel) has failed.
