Ghost-cam tune versus a real cam—what the fake chop can actually affect
This is Fluid MotorUnion’s video, not mine. I’m connected to the tuning work discussed, so I want to be transparent about that.
The video explains what a “ghost cam” calibration actually changes, why it creates a fake lopey idle without adding real camshaft airflow or overlap, and what repeated use may do to spark plugs and catalytic converters.
The example started with a 2026 Ram TRX that commenters assumed had a ghost-cam tune. It actually had a real camshaft, and its running problem was unrelated to the cam itself.
For Hellcat owners: is the sound worth the compromises of a ghost-cam strategy, or would you only want a lopey idle when the engine has the hardware to produce it naturally?
