Hey fellas I just an awsome deal on a dumaximizer so i hooked it up today, I tured the edge off and i could tell their was more power then stock but when i truned the nob it didnt seem to adjust, it seemed as if it was just stuck and the nob wasnt working, is it a very noticable power gain? can you tell from the nob all the way off to open? did i do something wrong? anyone got any tips?
