Why does my Rpms drop when I drive the truck in gear?
So I got my truck tuned about 2 days ago and it was running fine but I noticed the rpms where dropping to zero when I came to a complete stop same problem when idling it would be at 500 rpms and drop to zero truck does not shut off at all any idea on what it can be ?
Is dit een goede vraag?

Is the engine actually dropping rpms or is the gauge showing zero while the engine is idling normally?
