N55 DCT 100-200km/hr

In Taiwan, we get the Euro spec n55 DCT on our 335s as standard option.

Is there a big advantage considering the shift speed, transmission loss and weight?

I currently have iCarbon DP and JB4 stage2 installed, how would I go against a tuned N54 with DP?

Thanks in advance

DCT shifts faster, but during 100-200 run, it actually takes 2 shifts instead of 1 to accomplish.
I ran 10.2(P-box) on PSS tire. With everything equal, a modded N54 out-run a modded N55 on 100-200 run.

Thanks for the input! I'm not sure if I did it correctly, with DTC off, DP installed, sports mode button pushed without tune I got 13.6.

I will be testing it out sometimes soon when I replace my tyres, I'm also using PSS 18" but with 265 wide tyres.

13.6 sec without a tune sounds about right.
turning DTC off has no effect what-so-ever
PSS is so over-rated, I would take P zero RFT over it any day

Thanks dude, 10.2 sec 100-200km/hr is completely beyond my expectations. I thought I would probably get 12 ish!

How wide is your tire size? 255, 265? I got the m-sport 18" running on 265 wide tires. Thinking about changing it to 255.

At what RPM did did you shift? I always shift at 6200~ with the DP.

Taiwan has been raining alot recently, once the road is dry I will try it out with my p-box
