I have the Antec True Power 330w model. MBM is shwoing +11.38/-11.89. I am pretty sure from what I have been reading here that the -12v doesn't even matter, right? But +11.38 doesn't seem very good. Any ideas why it is like this? Does it matter? Can it be fixed?

You need to measure those readings with a multimeter to be sure, and yes -12v doesn't matter, it's just the +12v that you need to worry about. Spec is down to +11.4v, so that is out by a little, and still waaay lower than most would like

I was refering to ATX Spec, you are correct that with a Truepower line supply you should expect 3% as it promises. You need to grab a molex connect, shove the black (COM) from the meter into one of the black wire holes, and the other one into the yellow +12v wire. Make sure you are set in the right voltage range
Truepowers run around there. The rail being slightly low is completely normal, and within specs. You have 10% leeway to still be safe, so I would say that you are in good shape. If the psu has dramatic swings, then that's a different story.
It is rare to get a psu that runs "spot on" rail voltages.
11.38 is a bit low, however. The 5V rail is more critical. What does it read?

Don't trust MBM... it has to get it's voltage readings off a sensor chip on the motherboard. Lots of variables there to play havoc with the voltages. Multimeters don't lie if you're testing directly off a molex.
My True430 runs at around 12.03V and 5.03V, full load. Idle is pretty much spot on, 12.00V and 5.00V.
