07 Chevy 3500 Duramax Programmer

[omschubby]

My dad just got an 07 chevy 4dr 4wd 3500 duramax flatbed wants to get a mild programmer for it, just something simple to add alil power and MPG. I know you can go real big with a diesel, not trying to get into all that just a good plug and play one, any suggestions?

PPE and Diablosport both have a pretty good rep. Banks, superchips and hypertech all make a good tuner as well. I did a lot of research and I recently bought the PPE "Economy" programmer. I like it so far. It has a transmission relearn setting for new tunes, it defuels during shifts to avoid slip, my speedo is corrected, and it definitely gives it a little more kick and I am only running it on level 2. I don't know about the mileage yet, the next tank will tell the tale.

 

If you go too "hot" on the tune, you have to watch EGT's (pyro gauge install and/or new bigger exhaust) and a stock Allison doesn't like too much more torque input past stock from what I understand. Too hot a tune and you will slip/limp it, it is way to easy nowadays to tune the engine past what the transmission will handle without being upgraded as well. There is a ton of info on Dieselplace.com about programmers for the Dmaxes. Hope that helps.

I have the Edge EZ in my '05. It is plug-and-play and installs in minutes. It has 3 different tunes that can be changed with a flip of the switch. I don't know if they make it for an '07 or not...
