    My F355 MY97 with M5.2 runs at around 1300 rpm idle warm engine and it feel quite to high. Normal seems to be around 1050 rpm. What can the problem be or how to decrease? New idle speed valve or software upgrade of the ECU? anyone?

    Check for air leaks post throttle.

    Yes, check idle speed valve. Unfortunately, though, it may be time for adjustment of throttle bodies.
