I'm kinda thinking if I should get the AP for my MS3. My current mods are cobb intake, TP with stock CB and ETS TMIC. I'm pretty please with the power gain i have from these mods and not looking for more HP, but not sure if they are safe to run with out tuning!! I heard that our MS3 are known to run rich, so does that mean the fuel system is ok to support my current mods. Also, Do you guys thing I should go with the denzo one step colder plug? For the one that are using the AP right now, do you guys have any issues? It seem that many user have some kind of issues with the AP. At this point, I just want my car to run reliable.(spin)
