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 ?
Es esta una buena pregunta?

Does not give me any codes at all either

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