As of right the machine is doing maybe 2kb/s, but mrtg reads 25kb/s. I
tried changing the maxbytes but it didn't seem to alter it much. Would I
have to lower it?
Real reading from netstat:
netstat -w60
input (Total) output
packets errs bytes packets errs bytes colls

My guess is take a look at your mrtg.cfg file. By default mrtg graphs in
bytes not bits. Also having an incorrect value for the maximum speed of
your network card will give funky looking graphs. The two lines you want
to check are:
Options[^]: bits
and
MaxBytes[localhost]: appropriate value
when I created my cfg, with configmaker, it got the MaxBytes option wrong.
