Mercedes-Benz W213 E200 ECU tuning and bubbling

Thanks for your help.

This time we performed ECU tuning and bubbling installation on a Mercedes-Benz W213 E200!

Unusually, this E-Class is a female owner, the second since we started our ECU tuning and bubbling installation business lol.

I backed up the current car, tweaked the boost pressure and fuel mixture and made a test run. I did the first test run with the same upgrades as the data I have in my other M274 engine. Then the power didn't increase, the speed didn't change and it didn't go any faster at all - it was a 120,000km overdrive car, probably with the coils and other auxiliaries intact, and it was probably knocking. I will try a more gentle attack.

The car is tested many times and stepped on at full throttle!

How would you like to try it? If you would like to try it, please contact us! Best regards.

We are also looking for shops to become our dealers. For more information, please see below!
