Facts not Faith
You are more likely to do what you think is good. Whether or not that is actually good remains to be seen.
Religious people are more likely to adhere to a religious code than non-religious people. Sometimes of course, religious people break their religious codes because they are only human. Another thing to point out is that some religions do not have moral codes but most major religions do. Most secular people such as myself will at least in part adhere to religious codes. However, this adherence is not as rigid as that of religous people. The adherence of religious people to their codes is also affected by their interpretations of that code. This can be a benefit to their morality because the Bible and the Koran have many barbaric tenets that many believers either are not aware of, ignore, explain away, or refuse to follow.
For practical reasons, I am generally defining what is good conduct and what is moral to be honesty, not stealing, not lying, not murdering, being compassionate, being fair, being nice to others, not raping, being tolerant, etc. One big issue is that religious people can only be moral if their religious codes are moral. If someone believes in a moral code that requires them to kill infidels, then that code does morality no good. However, the perceived religious codes that most people follow today are moral for the most part. There are some issues with tolerance and open mindedness. Most Christians believe that they should not steal, lie, kill, rape and they should obey the golden rule and be compassionate. This will cause them to be more moral than a person who does not believe in a Super-Dad who is watching everything they do. As a very general rule, religious people are more moral than secular people. There are many exceptions.
