I have a 2019 S560 coupe. Time for a change. How does the power/torque differ between an S63 vs. a stage one tune on my S560? Looking for daily driver differences, if any. Thanks.

Anyone. Really interested in real world experiences with a Renntech tune on an s560 coupe (2019) M176 engine.

One member said it was really good. He liked it. If you boost the 4.7 it will add alot more hp and torque. So like most engines it will be a big improvement

But the 560 coupe only has the 4.0 liter engine?

bwaldmer

Both the S560 and S63 have the 4.0 liter engine. I believe the S63 has larger turbos and other upgrades to the engine.They stopped using the 4.7 engine after 2017. Model year 2018 onward has the 4.0.

I have a tune on my 2019 S560. Its the OE Tune version. its a huge butt dyno difference. I highly recommend doing one!

I have a C217 (550). And a GL 550. I can't speak to an S63 but I can tell you after doing a stage one Renntech tune I might well put a AMG logo on. This thing is a fkin monster now. Blazing fast and smooth as ever. I did the same on the GL. I throw that GL around like a car. Doesn't feel as pronounced as the S Coupe where you really feel the difference, you put it in sport mode and it just wants to take off. My truck keeps up with fast cars no issue. I love seeing the look on people's face when they see the kid hauler spank that ***.

You can't go wrong with the Renntech as the poster below said AMG = higher maintenance costs. And these suckers are expensive enough to maintain.

With the AMG comes all of the maintenance cost of the AMG.

I would rather have the smooth luxury performance and feel of the S560 tuned than the 63. Especially if this S560 is out of warranty.

2 different transmissions to account for as well

Is there a stated number of added HP and Torque anywhere?

You mean for the tune? If so it's in the Renntech website listed under the correct tune for your model.
