Most of their tunes are epa compliant. Working on this one as well. Doesn't delete anything at all.
Warranty is debatable since you can return to factory tune for reasons you may deem necessary.
To clear out all the chaff of advertising puffing here is a copy of Renntechs warranty posture:-

The legalese study is very reminiscent of Bullydog etc al who pedal these systems.
Of course its a free world, and you can do what you want!
Even set it on fire in a fit of temper or frustration I suppose , but clearly if you install this into your van and you have a serious mechanical failure other than claiming for an actual defect in the tune box itself, you are not going to get much financial relief if the engine goes "bang"!
OR all this extra power takes out your transmission at $6500 a pop.
Once I get some actual dealer info from an actual installer who is an MB agent I will post it.
Once again
"New lamps for Old" only really happens in fairy tales, those that your mother told you when you were a little kid.
