and the handhelds do very well with diesels.
Unlike gasoline engines, diesels don't have ignition issues. Just inject the fuel you want to burn and it'll do it. The transmission shifting is the only thing you might benifit but even then those HD trucks are very well optimized. I'd just go with a handheld programmer. They're easy enough to work with that anybody can use one.
