Hello! I have the following problem. I will start with a little bit history, i decide to increase the power of my clk 320 cdi, so i have overhauled my turbocharger with a bigger compressor wheel , than I go for remap. The guy said that the computer should be open in order to write on it the new data. So everithing was fine untill i went to the highway and step on full throtle. The problem is coming after 130-140 km/h before change the gear there is like a intermittent shut off the fuel utill change the gear, then it repeats again on the next shifting. This problem occur only on high speed with full throtle. What can cause such a problem? I forget to mention that , there is no fault codes and when i go for diagnose no body can tell me what is the problem. I id 7g tronic diagnostic and all was fine.
