These cars are very sensitive and the ECU has tight thresholds for boost so a boost controller is no good. The problem with a bigger exhaust is that it allows too much overboost and the ECU puts the car into limp mode.

And my boost also went from 10 to 18 psi Link to comment https://www.fordxr6turbo.com/forum/topic/80784-boost-controller-on-xr6-turbo/#findComment-1261953 Share on other sites More sharing options...

And as the ford doesnt run a airflow meter it cant compensate for it.
