Great write up, sounds really good.
I have just had my software upgraded and wastegates aligned, but I have noticed a lot of smoke coming from the exhaust on a standstill. I start the car in the morning, leave it running for 10 mins and still when I go into my boot I have to walk through a cloud of smoke. I expect some smoke due to the cold, but is this the norm??
