I have also heard that there are two theories for tuning this platform: leaner with less ignition and richer with more ignition. I have herd both sides form experienced tuners. I am not sure which is better but I do plan to test both. One thing i know is that DI brings new changes to the way we tune. I have a well revered tuner friend in the Subaru world who is running 12.5 on his modified 15 WRX with the turbo fa20 DI version. Normal PI turbo engines would have problems with this but he is having good results with leaner AFR. This was on a stock motor too.
