The Powermax cam has a longer duration and higher lift than the stock camshaft. This will result in more airflow into and out of the engine, which will increase power. However, it will also make the engine idle rough and may cause it to stall at low RPMs. To compensate for these changes, it will be necessary to adjust the fuel injection and ignition timing.
If you are not comfortable making these adjustments yourself, it is best to have the camshaft installed by a qualified mechanic. They will be able to make the necessary adjustments to ensure that the engine runs properly.
