Mountune Builds the highest HP 4 cylinder all DI engine ever ?

We’re always testing and validating engine upgrades and here we have an all DI solution in development for the 2.0L and 2.3L Ford Ecoboost. This E30 run on an EFR 8374 Turbo with our MRX cylinder head and built engine is at 684hp! Is this the highest all DI 4 cylinder ever?
Thanks to our tech partner @xtreme.di for the great components. Stay tuned as we continue to push the limits.
