I recognise this so much!
I once stood behind the car, and straight piped (valves open) at cold start you really experienced the pressure pulses at your chest while having 2 ears plugged with your index finger.
Once the wastegates close, there is the deep and dark rumble and suddely you recognise the 6 in line sound.
Problem is my dealer refuses to remove the cold start (they are able to do so with their specialist software apparently) |
I coded it off with BM3, but interestingly the car did not run very well for the first 5 minutes when cold. This was mainly at idle where it stumbled and hunted around for a stable rpm.
