A place that has worked on my engine before in Arkansas which is owned by a former detroit diesel tech. Talked me into programming the engine. This is my first road trip since having it done. This trip fort smith to okc is one I have done numerous times so I can compare accurately... 2 things I have noticed.. definite increase in power and my mpg is up 1.5 to 2 mpg at 67mph.. I'm averaging close to 8.75..
what did he change on the tune do you know? i looked into it years ago but was concerned about the transmission handling it and the cost. what did he charge for it?

He is super careful with the tranny.. I'm pulling 550 hp now .. he charges 500$
Do you happen to have his contact info available? Thanks
Yes he and his brother work together.. met these guys 3 years ago at
The Detroit diesel dealer.. they now are on their own. His name is Jason his brother is jamie.. number is 479-670-2710. They are located right off interstate 40 in Alma Arkansas.
Terrific, I'll give them a call... Thanks. Rick
On a side note does anyone know what rpms they are running at 67mph. I was at 1600 I'm now about 1420
unless i am missing something, reprogramming the ddec and or tranny should not change the actual rpms that you are running in 6th gear at a certain speed. it could potentially change the shift points, but not the gearing.

You are correct Tom, changing the ring and pinon gear would only do that. At least that is what I am thinking.
Maybe I am incorrect. But that's what I was thinking
