I’ve often read the term pre-tune checklist on various posts across facebook groups, forums, etc. One of the items that you may want to consider is replacing your Mercedes battery, regardless of how it tests if it is over six years old. There are two batteries on many late model […]

Replace or Upgrade Ripped Factory Air Intake Tubes
There are some options shipped, and I’m sure can be fabricated, that either seek to upgrade the air intake tubes or replace the Mercedes units which can get ripped. One option is using VRP or similar air intake tubes. Take this a step further by using wrapping the aftermarket metal […]
Lowering Modules Drop Your Airmatic Mercedes Electronically
The Air suspensions in Range Rovers have been modified for years. With links, later with GAP IIDtool and dealer programming to raise the height. The links are apparently super easy to install. But the computer way allows you to continue to run the car in an OEM fashion. For Mercedes […]
AMG Turbo Swap M157 to M278
One way to upgrade power on a (non-amg) M278 is to retrofit AMG turbos into the M278 engine. People on MB World report they bolt up directly and just need a tune to work and also routing of liquid cooling. One issue to anticipate is the M157 turbos have coolant […]
Pulley Upgrade Supercharged / Kompressors
One popular method of increasing performance on Supercharged cars is using a smaller pulley. The smaller gearing increases the boost provided by the supercharger. I remember my Dad changing out a SC pulley on a 4.0 or 4.2 SC Jaguar Engine. Nearly every aftermarket tuner offers smaller pulleys. UPD suggests […]
Cooling Upgrades
As Mercedes shifted into forced aspiration engines cooling became an issue intake air temperature (IAT), heat soak, and more were only exacerbated by tuning. Tuning Superchargers or Turbocharged engines often looks at increasing the amount of compressed air into an engine. Compressing air, as we know physics today, will always […]
Cold Intake Air Spacers
You may have heard about UPD air intake spacers, or Cold air intake (CAI) spacers, or VRP air box risers. Let’s answer three top questions about them. What are they? In various Mercedes engines the air intake is actually fairly good, especially when blessed by tuners such as brabus. However, […]
ECU Tuning & Hand Held Tuning Modules
With the introduction of the turbocharged Mercedes Engine line up beginning with the v12, v8, and v6, it was realized that there were more impactful gains to be made from simple ECU tuning than in the past. The levels of ECU tuning were no longer 10-30HP and quicker response, but […]
