If you encounter the problem that after the writing procedure of the modified file the RPM does not go up all the way and the power seems to be weak then just follow these steps.


Turn on the ignition and do NOT start the engine.
Leave the ignition in the on position for at least 20 minutes.
After at least 20 minutes with the ignition in the on position you can turn it off.
Start the engine.


The issue should now be fixed.
