I recently got myself a g27 and after 1 week I love it, but an issue has appeared. For some reason there is much stronger forcefeedback on the left side then the right side, massive difference bethween the sides, and it feels so wierd driving with it. Is there anything i can do?

What kind of games did you test it?
What are the ffb settings in your profiler?

Try the tests in the profiler, to see if the problem is still there
Try reinstalling the profiler.

If the problem is still there, contact logitech.
