C7.5 with sport package, got the EPL ECU/TCU and has been amazing. After that x-pipe and the sound is that much better as advertised. I got the VCDS and have just calibrated the ANC off and on but do far no change in that sound I hear everytime it is past 3rd gear and takes place around 27-33K rpm on light throttle acceleration. If I power through it it is no issue but I'm almost certain it is being caused by the 8 cylinder deactivation. Anybody else experienced this? It is annoying to hear it, to the pint that I might have to go back to resonator if the calibration does not fix it and it seems too loud to muffle out IMO.
I have also played with the soundaktuator, currently set at zero with no real change in that gurgle it makes...
