2021 AMG GT-R Pro Tune – Mercedes AMG

2021 Mercedes Benz AMG GT-R Pro Performance Calibration (DME Tune) developed by Cedar Performance & Utku Noa Performance

Looking for a 2021 AMG GT-R Pro Tune? Cedar Performance & Co. has been developing software for the M178 engine for quite a long time, with testing information dating back as far as 2017.

The M178 has proven to be a solid workhorse with few downsides, and has stood the test of time with some clients logging over 40,000 miles at 700+ WHP (dynojet).

Additionally, should you desire to push the limits north of 2 BAR, on the quest for 750+ WHP, our Calibrations Engineer Utku has 100% factory-like calibrations already dialed to ensure proper engine management at this output.

What kind of gains will I see?

• Stage 1 91 octane (95 RON): 15% HP / 20% TQ
• Stage 1 93 octane: 17% HP / 20% TQ
• Stage 2 91 octane: 21% HP / 25% TQ
• Stage 2 93 octane: 25% HP / 25% TQ
• Stage 3 93 Octane: 50% HP / 50% TQ 
• Stage 3 93 + Methanol: 65% HP / 55% TQ
• Stage 3 E85 fuel: 80% HP / 60% TQ
• Stage 3 Race Gasoline: 80% HP / 60% TQ

Tuning your 2021 AMG GT-R Pro:

The C190 and R190 are not equipped with CPC Modules, meaning these vehicles can easily be tuned to unleash their full potential!

Do I need a flash tool?

For Stage 1 and Stage 2 tuning you will need a flash tool only for remote tuning. Alternatively, a mail-in bench flash option is also available, and of course in-person appointments are also welcome.

For Stage 3 Tuning, you will often have multiple maps for multiple fueling options such as Ethanol, Methanol, and Race Gas.  We recommend purchasing a myGenius for this tune, so that you may switch files whenever you desire without our help.

Running Ethanol with my 2021 AMG GT-R Pro Tune:

While the M178 Engine when upgraded with Turbos absolutely loves Ethanol, the high pressure fuel pumps do not. In order to run Ethanol mixtures to make use of upgraded turbochargers, upgraded High Pressure Fuel Pumps are necessary. Depending on the pumps purchased, and the blend of fuel that is ran, it is possible to see more than 850 WHP (Dynojet).
