On my 2004 cayenne turbo, I have an EVOM intake along with other mods and an EVOM tune. I have been having issues with smooth delivery of acceleration and it has been suggested that it could be the EVOM intake causing turbulent flow and giving the MAF false readings. Any thoughts by those who have an aftermarket intake? Anything that can be done beyond replacing the stock intakes. I have checked all the other potential issues (ignition and fuel system, pressure test)

 

I think your question is better suited for those with EVOM intakes. I, and many, have aftermarket intakes - with no negative issues - but not the EVOM.

 

I have an 04 Turbo. After intake everything seem fine. I don't have EVom intake. It's more like custom made. Same concept. I will check for leak. Use durametric to scan for codes. Check you diverter valves. One of them might be stuck open.

Last time i lost power. My fuel injectors went bad. Was able to drive but not more than 100km/h.
