A drive in the Carrera T and GT3 Touring

This is the thing that makes me doubt. My DD is a BMW 440i AT and while I readily admit there is no comparison I find the 440 horrible off idle. You can really tell when the turbos drop out and it’s not even very repeatable. It really compromises the experience for me and is one of a few turbo impressions I have that are not favorable.
But it perhaps the variable vane compressors and the ability to blip an MT to keep them spinning is enough to make the difference?
My 991.2 GTS has zero of these characteristics. I honestly don't really notice any turbo lag in any kind of driving. Porsche did an amazing job with this engine, and they've done a much better job than BMW on their turbo engines. There's power everywhere, right from the start at low RPMs.

Very helpful comments - thanks all! Definitely giving me something to think about...

I have a BMW X5M as my daily, and it's really obvious that it's turbocharged. Below 2500 or so it's a dog, and then the power comes on strong. Because of this it's really only enjoyable to drive in transmission modes that keep the RPMs high. In normal mode it's frankly dangerous to drive, because you either have no power or all the power, I almost got into accidents when I forgot to put it in sports mode.

Terrible that BMW still hasn't fixed this.

Yeah, I had that same issue. It's not the turbos themselves, it's the throttle. I distinctly recall calling the car dangerous because you'd try to get in the gas and pull into the intersection and it'd be nothing.....nothing.....nothing.....BAM IM DOING A BURNOUT AND GOING THROUGH THE INTERSECTION AT 65 MPH!!!!

These is only one fix for the Bmw and mini which was to install a sprint booster on the throttle.
Once installed we instantly fixed this issue in all driving modes.

We recently purchased a Mini Countryman in a manual transmission and experienced the same horrible delay throttle issues. We were shocked and appalled that the Bmw programming will not allow the car to go!
