2016 6.6 Duramax Tuning

[426power]

Looking for recommendations for a good tow tune. I want something hand held that I can put in and take out when needed. What tuner (company) seems to have the best tunes and which handle held tuner is the best?

You're after 'emissions in place' tuning?

Really not available. If you want a tune its really delete the dpf and lose warranty.

The SCR and DPF really last a lot longer and few problems when the EGR is shut down.  That can be done via software.  Kennedy does it.  I have found just shutting down EGR reduces many problems and allows many diesel motors do a pretty good job.  Greatly reduces soot loading of the oil also.  Not one negative thing and the easiest, least costly thing one can do to improve diesel motor performance.    Warranty far less in jeopardy.
