We review the performance of a Blouch DOM XTR1.5 on a 2018 Subaru STI RA

The fuel available is non ethanol pump 91 which is about the worst fuel for turbocharged cars. With some ethanol there would be substantial gains.

This is not a huge turbo by any means and you can see it adds a heathy margin over the stock turbo.

Tune done on our Mustang Dyno.
