A tune can only work with what the engine's giving it β and on a high-km diesel, that's often the injectors.
Worn injectors spray fuel poorly, which means uneven cylinders, rough idle, blacker smoke, and power that just isn't there no matter how good the map is.
Signs to watch for: rough idle, a fuel smell, increased smoke, or a drop in economy that's crept up over time.
We test, recondition, or replace injectors as part of the diagnostic process β because a tune on top of tired injectors is just masking the real problem.
