I have a 2009 GMC 2500HD diesel. The tech when asked privately said not to use the Predator on this engine as there were too many electronic feedback loops, etc. Obviously they are sold and I have one. Could you comment on his comments? Thank you.

Never heard of such a thing....he may have been referring to the DPF system and its emissions monitors, but the Predator will not affect them at all.
