The million dollar question. For the 05-06, I don't think the stock tune is questionable on a 100% stock car. But I can't say for sure if there is an inherent design flaw in the motor which leads to the ringland failures. Nor can I vouch for the quality of everybody else's tunes. But I do believe that the Subaru ECU is very forgiving and has an aggressive knock control system, IMO more aggressive than any other turbo car I've ever messed with. There are so many cars out there that if you make one mistake, you're dead.
