GLE 63S (W166) and Renntech question
Hello ladies and gents,

I was wondering if anyone here has any experience with a Renntech tune for their W166 GLE 63S. Thinking about adding and was hoping to hear some feedback from someone who's done it. Thanks in advance

Get the R1 pkg. I have it on my 2013 E63. I plan to put it on my 2018 GLE 63s coupe soon.

Its quite enjoyable. Maybe not for the tires though.

With this after market tuning, be it RennTech, QEtuning, or any other tuners, would the remaining warranty be voided?

I've got it on my '16 GLE63. Power, torque, and sound (in Sport+) is insane. I get 12-14MPG here in Colorado.
