This is a question Ive been trying to find an answer to for quite awhile.
Does anyone know what the differences between the 150 and 200 HPDis are?
(Without the obvious response of 50 HP:rolleyes:)
Bore , stoke and compression seem to be the same. Obviously there is no camshaft to attribute a hp increase to. The only thing left seems to be ECM programming. Maybe injector size?
Could extracting another 50 HP out of a 150 be as easy as an ECM switch ?
