if i was modding or modded id get an aeroforce, wideband, and oil pressure but since im not those would be pointless. I'd like to have an volt gauge cause i got lots of **** run though that thing and itd be nice to have so i know whats going on and itd be actually useful, same with the mpg one, since i dont have anything telling me what it is at all that one would be nice to have also and be useful at the same time
