Not sure if anyone has confirmed if this works yet.

^ All those things do is just change the value of the throttle input the car sees. For example, the same 40% throttle input will be read as 60% with those modules installed vs not. That's effectively what the Sport+ mode does with its throttle mapping.

I do think that shifter kicked to the left helps it feel a little more peppy though.

And I do believe there is a solution. I believe there's a module called the Sprint booster that allows you to adjust throttle response. I think it's a plug and play unit.
Note that change in the value of the throttle input the car sees isn't the same thing as throttle response. The former refers to how much is outputted while the latter refers to reaction speed of the car to one's input. By making the output greater for the same input, it can be made to seem like it has faster response when in reality, it just requires less input.

As for the shifting being on M/S, that may be faster but according to the chart, it's still not the fastest shift speed.

Lastly, I'm not sure if there's a measurable difference in power output (read: aggressive engine mapping), but if there is, then that's another area where you're at a disadvantage by being in DSC Off vs Sport+.

It's even worse when you add more power, feels like big turbo lag! Sport+ makes the car feel like it has a NA V8 w/ 500hp ready to crack a whip, lol.

I too would love to be able to use Sport+ throttle, with DSC off. I think the only way to do that, today, is with a Sprint Booster or alike product..

I've asked before, but can DSC be coded out, completely? Including the EDS (ABS LSD) and all..
