GTS TCU tune worth it?

I've read mixed reviews.

It’s worth it. I use the Thor flasher app but you can also get the same done with BM3 or MHD.

Worth it for more than just clamping. It changes overall shifting behavior enough to make it a much better experience.

It's kind of the difference between an amateur with a manual trans and someone with experience. The shifts are faster but you don't get the "dumped clutch" feel all the time, there's less lurching - especially on downshifts - and the automatic mode feels much smarter.

+1 The stock TCU was rough in stop and go traffic. GTS flash made a huge improvement. It's less jerky, and shifts feel more firm.

Any side (ill) effects? On a stock 2017 model Non-CP car?

Mine is a non-CP 2016 with just a BMS stage 1 and honestly the only regret I might have is not having done it sooner. The GTS tuning for the DCT has no downsides at all that I've ever experienced. It's better at shifting and clutch engagement when you're at full throttle, when you're stuck in stop-and-go traffic jams, and everything in between.

Is it worth it or noticeable on stock or CS tune?

Does the bm3 gts TCU tune have any install issues on 2018 cars?


Yes ~ It is worth it. In my case, it was free of charge since I went with BM3.

The gear change is very noticeably faster, smoother. I auto-shift mode ~

coming to a stop, change from 2nd gear to 1st is more natural with GTS \

tranny tune.

If people claim they cant feel the difference, I don't know why they are

driving M3.
