I was told you can increase the power of a transformer by changing its x/r ratio. You don't need a larger transformer to produce more power just change the x/r ratio. Is this true?

The X/R ratio of a transformer is determined by its design and construction. After it is built there is nothing for you to change.
I had a 3MVA trasnformer core/coil inspection and it failed the X/R ratio. So they went back to make adjustments and managed to bring it into range. Granted the adjustmens that can be made are minor and has to do with clamping and tightness, but SOME things can be done.
But all they did was bring it back to its design X/R. They did not change it with the end result being to change the output of the transformer.
If they could not restore the specified X/R, what ould have been the next step?
Certainly the 'tightening' of the X/R ratio slightly changes the transformers capacity, but not to the degree the OP implied his needs, which he did not state with any quantitative values.
I was interested in what you would have done if they could not bring the X/R ratio back into specifications.
