How can i optimice this FOR sentence with lots of IF?

It takes too many time to run one for iteration because the quantity of if in it, if its a better solution for it and someone can help me i would be very greatfull. The function works a singular code with the items detailed in IF sentences time by time. With a list of 2000 3000 codes it takes too much time and ejecutions because the 6 min max time expires frecuently.

function CODIFICADOR() {

  var sheet1 = SpreadsheetApp.getActive().getSheetByName('PROGRAMA');
  var cantcod = sheet0.getRange("B1:B1500").getValues().filter(String).length;
  SpreadsheetApp.getActiveSpreadsheet().toast('POR FAVOR NO REALIZAR NINGUNA ACCION MIENTRAS EL PROGRAMA SE EJECUTA');

   for(var i = 2; i <= cantcod; i++){
    var codigo = sheet0.getRange(i, 2).getValue();
    var codigosig = sheet0.getRange(i+1, 2).getValue();
    sheet1.getRange(2, 8).setValue(codigo);
