Hello all,
I am a Porsche Macan 2.0 owner and I have been following this forum for quite some time. Unfortunately there are almost no enthusiasts that modify the Base Macan that shares the same engine with the Golf R (EA888 Gen3 2.0 TFSI). So I thought it's best to sign up and shoot my questions out to you.
I have recently rebuilt my engine following an unforeseen engine failure and used forged internals this time.
About my vehicle:
It’s a 2017 Porsche Macan 2.0
I am now in the middle of getting the tune done via a e-tuner and have an issue that bugs me. I want to see if this is tune related or a mechanical issue that needs to be solved.
The problem is, when I go above 4000rpm and let go of the gas pedal quickly, the rpm hangs and slowly decelerates (normal behaviour to not to shift up in sport plus mode). If I press the pedal again, the rev stutters, car feels like the fuel is cut, I hear pops and bangs from the exhaust and rpm is not picking up. Otherwise if I floor the pedal from any gear or standstill, no problems. Video is also attached. What could be the reason? Thanks a lot in advance!
