Your meters are probably right. There's most likely still a lot of peaks. If your using a DAW set your meters to read RMS if possible or in Sound Forge when you have the Normalize window open you can scan for levels both Peak and RMS. Compare these readings to something that sounds similar and is professionally mastered. My guess is you probably have some more processing to do to get on the mark. Remember these 2 things though.
1)This is one of the most difficult things for a home recordist to achieve with limited gear and knowledge. (I'm not calling you an idiot, but there are people out there who have the gear, ears, and much more experience than most of us!)
2) Is it that important for your CD to be loud? I would not destroy a mix by overcompressing and limiting just for it to be loud. Current trends towards making a waveform draw look like a solid colored box have made most modern music lifeless and having little or no dynamics. If it's something you consider "important", let a pro master it.
