Tuning, Race Parts, Accessories
We go deep on the upgrades that unlock your Mercedes: ECU/TCU calibrations, intake systems, turbo paths, and cooling—backed by logs and dyno results.
Expect side-by-side comparisons, installation notes, and practical guidance to match parts with goals—daily drivability, track days, drag passes, or towing.
Build smarter, not louder.
Mercedes just announced their new C63 will be a 4 cylinder hybrid platform, and they have released information about their electrified “73” platform. These utilize a rear limited slip differential with a integral motor with 2 speed transmission. This is quite a departure from the 53 platform M256 E30 . Which […]
Choosing a tuner and performance parts suppliers are important decisions, unless the car is a true project car. There are a few questions you may want to consider before choosing. Who are you dealing with? What is their post/social history? What is their bad reputation? Can you deal with their […]
I’ve been running a TCU tune for more than a month and several thousand miles. In this video I discuss some of the reflections and drivability of running a Morendi TCU tune.
Still in progress check back later! One of the increasingly popular discussions on FB CLS and, of course, tunedmercedes group is building custom air intakes. Apparently the black box dynos have been confirmed as real by a few people but most of those gains are for “tuned cars” with waste […]
MBworld.org has some amazing knowledge. It is a little deep though to dig through, and it isn’t always the most intuitively laid out. Here are two of my favorite threads on MBworld. Build the most powerful CLS 550 4matic is one of my favorite threads on any forum hands […]
Check out this install thread on MBworld.org for AL Priority Laser on a w212. Very clean and detailed with some help from other members with CAD information on the mounts. I am not advocating the use of this, but I do love clean installs and have to link to it […]
I recently picked up a Dragy which is a 10hz GPS sensor that can track your performance data. This is pretty cool. BUT the really great part is that you can see the leaderboards by make, comment on other’s times (and receive replies). Which can really demystify tuning. One example […]
If one (yo Gilles this is for you bro! ) were going to buy a completely stock M278 based E class or CLS and build it out, here is some guidance: Pre-purchase Open up the hood, take off the engine cover, lifts straight up with tabs but take it slow, […]
While there are conflicting reports about the logic of the intercooler pump. With mine it didn’t run all the time (you can hear it before she comes up to speed), and with this mod it did. With this mod you get lower IATs. Check out here: https://mbworld.org/forums/w212-amg/785054-reduced-iat-s-pump-rewiring.html I’ve heard a […]
Adding an oil collector on a direct injection engine can help maintain horsepower and mitigate issues with carbon build up on valves. I first heard of them reading a online forum “discussion” between two tuners and one brings up GAD tuning. One thing I realized there are tuners that I […]
While AMG’s and Brabus sound crazy to begin with, Mercedes engines often have a quiet growl, perhaps especially their V8’s and V12’s. One way to wake the sound up, especially with the m278 engines, is to delete the center resonators. This produces a nice deep boat like cold start, great […]
If you are looking for what a mercedes engine makes tuned you have found a good article to answer the question how much horsepower does a tuned mercedes engine make. M276 V6 Stock Rated 328hp 350 Tq Tuned ~410hp ~ 464 Tq Source OETuning Sold as 400, 450 M278 Stock […]
For some models like the C218 there are air dams in between the grill and the air intake tubes. In the past I haven’t messed with these too much as I have had some weird noise issues from modifying these in the past. Well. No worries here with noise. It […]
Spark plugs actually have a temperature range that they are designed to operate in. A colder spark plug doesn’t fire colder, but it does help evacuate heat from the cylinder head faster. Pressures with emissions and finding the right balance between a spark plug that will burn fuel completely even […]
As the push for ever increasing fuel economy has pushed engines to be more efficient and use innovative technology we may not otherwise see, there are some configurations of Mercedes that run a dual battery set-up with one battery primarily, to my knowledge, to power start the engine and power […]
