We at Crawford Performance will start this by stating the number one issue responsible for the damage to Subaru engines is the free software available on the internet to modify the tuning parameters within the ECU. There is plenty of bad advice going around but the most common one I hear is "the bigger or looser the piston or bearing clearances, the better the engine will perform." Another is about larger pressure/volume oil pumps are always better because the factory oiling system on the EJ motors are inadequate, when in fact, a high-pressure oil pump can cause oil cavitation while lowering the ability for any oiling system to work efficiently. Another falsified fact is using a lower-temp thermostat will make your motor run cooler in hot weather but in reality it will have zero effect on increasing your engine's cooling capability. Other falsified facts include tuners believing that installing 1mm oversized intake and/or exhaust valves over the stock size valve seats will increase cfm airflow, and the best of all that makes me laugh every time I hear it is "you can make 500 whp safely on pump gas."
