What kind of regulator do you have right now? Is it an external regulator, or the stock internal regulator that came with the alternator?
What kind of batteries are you replacing?
All battery types will benefit from a "smart" external voltage regulator that will customize the charging profile to the chemistry of the battery type.
But one of the advantages of AGMs is that they are fairly forgiving when it comes to charging. You will get optimal performance with the custom charging profile, but you will still get very good performance with the same internal regulator used to charge standard wet cell deep cycle batteries.
So if what you have right now is a standard internal voltage regulator, which has been charging a bank of wet cells, you will be fine with the new AGMs.
If that internal voltage regulator ever fails, consider upgrading to a "smart" external voltage regulator.
