As you did, I assumed he was a noob asking some retarded question. But, if you had read the thread and not acted like an immature fool, you would have understood his question. Next time, why don't you read the thread before posting, please?

If you're still maintaining 13 volts at full tilt your set up is fine just how it is.

The deal with high output alternators is to support Extremely high power systems in cars with smaller output unit. Some imports have 70 amp (cruise output) alternators so huge systems (say a 1000W system) are going to hog all of the power.

Also Pickups/SUVs with high power accessories (lights winches e-fans etc) require great deal of power to run especially at lower RPM

This is one of those situations where the demand says you need bigger than 105A, but the results say otherwise. It's why people always say install it first and see where you're at. Appearently, you're fine.

However, in the long run you may see your voltage start to fall, so keep an eye on it.

Are you sure a 04 Tahoe only has a 105A? That seems pretty small to me..my Explorer has a 130A i believe...
