Nice gains. Glad to see more tuning options for this motor.

This motor is not going away anytime soon.. so hope we can see increase after market products.

This car needs better intake pipes and boxes. They are tiny.

Also a proper dual exhaust option (Not a Y config as stock)

Turbo outlet/charge pipes are easy to reach and should be a easy swap for larger ones.

We agree. A better intake system, exhaust system and cooling system will further improve the vehicle's performance.

All of our AMR Performance ECU Upgrades (tunes) are designed in-house specifically by our software engineers & ECU calibrators. So the "tune" is to our own coding & design. Because of this, we can operate under our own conditions & requirements which give us the ability to do more in-depth vehicle & ECU analysis as well as testing to ensure the vehicle is operating within strict industry standards while satisfying the enthusiast crave for power without sacrificing drivability or reliability.

Are these wheel or crank numbers? Also, would this be the same tune that you'll use for the C450 since it's the same engine which puts out 362hp/384tq stock?

Is this the same 2.0l engine that's in the C200 (Japan / Euro)?

I don't recall the engine model number...
