Over boosting typically occurs under certain conditions:
1. Vacuum leak(s) found between the intake and turbo.
2. Running incorrect modifications for the map
3. Boost pill removed
If your vehicle is still exhibiting over boost conditions, we offer low wastegate maps. These maps will adjust your current calibrations to mitigate the issue. You can find these maps here: Mitsubishi AccessPORT Off-The-Shelf Maps.
