This sound has been recorded on a real R450 NG Scania with my Zoom H5.
These two sound mods work with the SCS trucks and the PGRS series by Eugene.
Improved the DC13 (6 cylinders engine) sound.
As usually, all sounds sliders in game sound options should be at 50% (default settings).
Compatible with 1.46
