More engine power

Anybody have any experience with tuner or performance updates on the 2018 Mercedes engines?

Any long term reviews?

I am interested in having MB dealer do Renntech.

Not looking to delete., But have conserns about the affects on exhaust filters.

99% of my driving is highway speeds (under 70mph) in rolling hills of east coast

But please don't post non Mercedes input or your opinion on upgrades in general. Only looking for experience with Mercedies

Thanks

I would be interested to hear what is available for the MBS also, I am looking for some additional performance but am looking at mpg. I have a 2018 2400W and sometimes tow a 2015 Jeep Cherokee. Thanks

There was a story on the Dynamax forum about getting 75 more horsepower out of the 3 liter.

Me too , even towing a 3,000lb trailer the cruise control handles most grades with no slowdown.

What weight are you towing ?

I really wanted to do this, BUT. I have called several local dealers, and they all say "we have stopped offering this software". I asked questions and it seem to be related to related to warranty and "what if". I understand I can buy it mail order. the Manufacture is 2 hours SE of me, and the East coast distributor is an 1 our NE of me.


and its working pretty nice without it.
