No experienced tuner will alter only the pressure on the common rail...plug in boxes do this and are useless in comparison to professional ecu mapping.
We adjust not only inj quantity, ibut also injector pulse/open time. We race BMW diesels and tune them for other race teams in the Dunlop Maxx series and similar.
You will see approx 35hp - 40hp increase. MPG improves according to driving style.
Any other questions, please ask
