Hello
Just got a 2014 3500 6.7l (not running at moment) but read that the deletes will lower EGT's and increase mpg's and possibly engine life (Mines has 136k). Can the stock exhaust parts be reinstalled if necessary (bolt on)?

I understand the EGR delete but what does the throttle valve delete accomplish?

Which tunes/tuner are recommended for the 2014? How much extra hp can the engine stand before risking HG (or other) failure?

Thanks
