Just Picked Up A 2019 GLS63 AMG!
Renntech sells an OBD2 lowering module for the GLS but it is expensive.
Is this the one on Amazon? https://www.amazon.com/Mercedes-Benz...r=8-1-fkmrnull
The link you you posted is the one I am considering. $450 not bad at all!








Also, anyone here actually have a burble tune from one of the tuners? I find the GLS in Sport+ is MUCH quieter than the GLE S we just had, which was a BEAST (factory) in Sport+ mode. By far the loudest and nicest sounding OEM AMG exhaust I've heard.

The Best of Mercedes & AMG






Good to be back in the AMG game! Just picked up a 2019 Diamond White GLS63 AMG and am loving every minute of it! I had to baby it for the first 1k miles in Comfort Mode and keep it under 4500rpm. It was hell! But now that I'm done with the break in period I have been applying more throttle and revs in Sport and Sport +. I believe these cars have an adaptation phase in the first 1k miles to learn your driving but I'm not sure. Im at around 1400 miles now and the car just keeps getting faster and more responsive! It just shocks me that such a big car that seats 7 people can accelerate like it does. To me this car has no competitors because it can seat 7 reasonably and run 12s in the quarter mile.
The differences between the drive modes are very noticeable. If you are in stop and go traffic, the transmission gets fidgety in Sport +, so I mainly use Sport in slower traffic. Comfort Mode is very laid back and smooth which is good for long trips.
I ordered BMC Air Filters for the GLS63. Anyone have any good experiences with these air filters?
I'm sure with a Renntech Tune and Capristo Exhaust this car can come to life as a beast and maybe even runs 11s. Maybe. Cant wait! Anyone know of any other exhausts made for the GLS63? Also, is Renntech the best choice for a tune on this platform?
Look forward to making some power with this AMG! Glad to be on here again as MbWorld has served as a great source of information about our AMGs.
