El Presidente our glorious plan is to uberpower election cheat option.

Stage 0. Backup
If something going wrong backups are our oportunities to fix the game. In the Tropico 5 install folder you can find subfolder named Packs. There are a lot of .hpk files.

• Make copy of all .hpk files from Packs folder before you'll made any changes. Or you can make copy of entire Packs folder.

Stage 1. Unpack

• Launch HPK Archiver
• In Game section chose Tropico 4 / Tropico 5
• In the Extract section choose to open Lua.hpk file which can be find in Packs subfolder of Tropico 5 install folder
• Create your working folder ( My working folder is G:\Tropico 5\Packs\Unpacked\) and subloders for unpacked files ( for this tutorial I will use G:\Tropico 5\Packs\Unpacked\Lua.hpk\ folder)
  
• In the Extract section choose folder to unpack the files (I will use G:\Tropico 5\Packs\Unpacked\Lua.hpk\). Use different folders for different .hpk files.
  
• Hit Extract button.

Stage 2. Decompile
In the folder where you unpacked the Lua.hpk you can find a lot of .lua files. We are interested in Tropico 5\Packs\Unpacked\Lua.hpk\Lua\Game\CityElections.lua. Some files could be decompilled with iGO decompiller but if you see the error log with decompilled files this is not the option. So we will use unluac.

• Extract unluacv1.2.2.zip to your working subfolder
• Using windows Explorer navigate to folder where you created the working subfolder shift right click on the working subfolder and choose the Open Command Window Here option from context menu
• In the console window type this command

  java -jar unluac.jar Lua.hpk\Lua\Game\CityElections.lua > Lua.hpk\Lua\Game\CityElections.luad

• The file Lua.hpk\Lua\Game\CityElections.luad is the source code. You can use any text editor to modify it.
• Don't close the console window you'll need it on Stage 4

Stage 3. Make election fraud uber

• Open CityElections.luad with any text editor.
• We are interested in function City:GetElectionSupport(cheat). Find that line
  
• Few lines under you can see interesting line

  local converted = Min(against, Random(3 * self.VoteFraud, 7 * self.VoteFraud, "election_support"))

• Change it so we have more percents

  local converted = Min(against, Random(53 * self.VoteFraud, 57 * self.VoteFraud, "election_support"))

• Save changes

Stage 4. Compile

• Lauch iGO tool
• Hit compile button and choose Lua.hpk\Lua\Game\CityElections.luad
• If there is appeared 2_CityElections.lua then delete the original CityElections.lua
• Rename 2_CityElections.lua into CityElections.lua

*If 2_CityElections.lua not appeared then there is some compilation errors

Stage 5. Pack

• In the HPK Archiver in Acrchive section in the firt field choose the directory where you have unpacked the files (im my case is G:\Tropico 5\Packs\Unpacked\Lua.hpk\)
  
• In save file field coose file to pack (in my case is G:\Tropico 5\Packs\Lua.hpk)
• Don't forget to make backup before overwrite the original file
• Untick Compress It checkbox
• Hit Archive button

BTW it seems it is possible to mod the game without repack http://forum.kalypsomedia.com/showthread.php?tid=22981
