In UVHM, enemies regenerate health. Are you Slagging enemies before switching to an appropriate element weapon? In UVHM, a Slagged target takes 3x normal damage. While it isn’t a requirement to Slag targets in UVHM, it makes playing the game easier. Maya doesn’t really need a weapon to Slag targets, since she has Scorn and (Converge + Ruin) which effectively functions as a Slag singularity grenade without the need to carry an actual Slag singularity grenade. However, it might be a good idea to carry a source of applying Slag as a backup. A few things I can recommend include: a lower level MMx4 grenade (since you are mainly interested in applying Slag), a Florentine (Shock / Slag) SMG, the Slagga (Slag) SMG or even a decent Maliwan or Hyperion brand Plasma Caster (Slag) . Those will all get the job done of applying Slag to a target.
If your weapons are not at least within 4 or 5 levels of your character, you might want to consider redeeming Shift codes to get Golden Keys. You can then use the Golden keys on the Golden Chest in Sanctuary. In UVHM all of the items you get will be at your current level. You will never get a White or Green item. Most of the time you will get 2 items, and they will usually be Purple. Sometimes they will be E-tech. You will only get a Blue item if that item is a Relic. You will only get 1 item (instead of 2) if the item is a Rocket Launcher. Lastly, you cannot get Legendary, Seraph or Pearlescent items from the Golden Chest.
You can also tip Moxxi to get a Good Touch (Corrosive) SMG and a Bad Touch (Fire) SMG. You can only get 1 Good Touch (Corrosive) SMG per character across all playthrus for that character. However, you can keep tipping Moxxi and keep getting a Bad Touch (Fire) SMG as you level up in UVHM. I also recommend farming Knuckle Dragger for a Hornet (Corrosive) Pistol. He is the easiest Boss to kill and you should be able to get a decent at level Hornet (Corrosive) Pistol for Maya. The Hornet (Corrosive) Pistol is arguably the best Corrosive Pistol for Maya and typically the only Corrosive weapon I equip, even while helping people thru the OP levels at DigiStruct Peak.
If you are still having some difficulty with Maya in UVHM, using the following link and posting the results in this thread will allow us to give you some recommendation for your build:
The following is a Build for use with the Legendary Siren COM and ideally a Bone of the Ancients Relic. It is similar to my own Siren build, but designed for a level 59 Siren. It even has 1 point in Cloud Kill, since the 10/29/2015 patch buffed that skill :
Assuming you can get to at least level 61, the following is the same Build as above except for 2 points that I put into Elated. It is designed for a level 61 Siren:
