If the code is missing, it usually just means its using a bf2 default setting which doesn't require the code, same as how a lot of handweapons don't have MagSize specified, but the bf2 default gets used anyway.
Just copy and paste the lines from another tweak that does have them and you should be fine. Also, please don't double post, its against forum rules and one of the dev team is in here multiple times everyday. We're only 5 guys and we can all only be here at certain time zones, so chill out if we don't answer immediately. For instance, when you posted this question it was 3:25am my time and I had only just gone to bed, lol
