Meth give more power at the same boost. It cools the charge through evaporation meaning more oxygen density, and it increases the octane meaning more ignition timing. Both together would give 30-40hp at the same boost. Then the higher octane means you can run more boost which means even more boost as in this case with an extra 50-60hp.
