For Ford's 6.7L Power Stroke
Check out Maryland Performance Diesel's fix for the restrictive, failure prone turbo on '11 to '14 6.7L Power Strokes...
The guys over there ditched the factory dual compressor wheel'd GT32 SST in favor of a BorgWarner S363 off a common-rail Cummins, and fabbed up a different mount and intercooler piping.
The MPD team also addressed the Bosch CP4.2 high-pressure pump's lack of ability to support max-effort tunes with stock injectors (maintaining rail pressure is the issue) by adding a belt-driven CP3 up top.
With custom tuning using H&S Performance's MCC software, the '13 King Ranch F-350 dualie graced with this setup laid down a strong 607 hp and 1,225 lb-ft at the wheels on a 248C DynoJet. Not bad for stock injectors and the factory 6R140 TorqShift!
