All I'm trying to say here is if you plan on modding source tuning options. Tuning helps you extract more power from the mods you do, and helps your engine to run at peak efficiency. Do I expect everyone to think of tuning first? No, but since I clearly hold tuning in a higher regard, I look for tuning options before anything else. Call me crazy.
