Alpine ECU tune + GTS DCT tune + AA Test pipes = TOTALLY DIFFERENT ANIMAL!!!
As the title reads, I just got these mods done on my 1 month old (new to me) E90 M3.
I drove it stock for around 3 weeks before I got the Alpine ECU tune and GTS DCT tune. I'll be honest, I didn't feel much of a power gain from the ECU tune according my butt dyno.....although Alpine claims a 20-22hp gain. Maybe the butt dyno can't detect a 20hp bump? Or maybe my car was already tuned by the previous owner? The GTS DCT tune is a MUST do mod for this car. Totally changed the smoothness and shift speed of the DCT transmission. At $100-$150, it simply cannot be beat. Active Autowerke test pipes (primary cat deletes), they were $270 shipped (5% off coupon). I just got these installed today and I can feel what a difference it made. They advertise a 20hp gain, and this one I can actually feel something on my butt dyno. Sound wise, without cold start delete it idles slightly louder than stock. After 45 sec - 1 min it idles as quiet as stock. Under 3.5k rpm, it is maybe 8-10% louder than stock....around 4K RPM to redline is really when it roars to life!!! The soundtrack is incredible....sounds SOOOOO mean/aggressive like a race-car engine should. The downshifts sounds so good. Imagine doing 60mph in 6th gear, you click the left paddle 3 times, now you're in 3rd gear. Foot to the floor and you just take off. By the time you shift to 4th gear, you're doing well over 100+mph.... Although I've only had this car for 1 month, this is all the performance mods I intend on doing for now. There are some cosmetic mods to be done, but that will be it. Next year, it's time to go supercharged with the ESS VT2-625 kit and rod bearing replacement.

Nice.
I was thinking of going with a Dinan Trans tune or GTS DCT. My mechanic does the Dinan tune for around $250 and TopGearSolutions and AlpineMSS can do the GTS tune for $60 to $70 for remote coding. |

Not sure how different the DINAN trans tune is but you can't go wrong with BMW OE software. Get the GTS tune!!

I read something a few days ago that the "GTS" tube actually softens the shift in the higher "S" settings and that it actually makes the car slower in full bore acceleration. Is this BS?

I believe the Dinan and GTS DCT tune are the same. Could be wrong though. I think I paid 100 for the Dinan tune.
One should certainly get one or the other though, totally changes the feel of the car and removes a-lot of the clunkiness.

I'm not a fan, but allegedly it increases the longevity of the DCT so I kept it. |

You will receive a OBD2 cable that will be locked to your VIN. You download AMS software, and use that to upload the tune to your car. Takes around 5-7 minutes to upload a new tune/map.

I would do this: Get the Stage 1 and Stage 2 (catless) tune from Alex first. Upload the stage 1 tune to your car and leave everything else stock. Drive it for a week and see if you notice any difference. Then add the GTS DCT tune to the stage 1... Lastly, get the test pipes put on and switch to stage 2 tune with burbles. Are you choosing the burble option?

Not sure if you are aware, but you can hold the downshift paddle (left) and floor the accelerator and it will drop down many gears. Saves time from clicking 3 or more times. It will automatically drop to the correct lower gear and power range. Just be prepared to upshift fast. 🙂👍

This is supposedly what shipped with the GTS.
-Smoother and smarter transmission settings in general. - S1-S3 do not blip downshifts, they slip downshifts. For this reason I use S4 for most driving. -S6 will ease into upshifts when around quarter throttle or less, no shift shock, stock US / Euro would upset the car a lot if you did this. -S4-S6 slam into upshifts, absolutely no cut of power, will really spin from a 1-2 gear shift, 2-3 will sometimes spin even on a hot day. -Been a minute but I believe launch control was like 3500-4500. Hooked up much better than the stock tune, which just spins tires. -Sounds (exhaust note) like a torque converter automatic, meshing into upshifts. GTS DCT tune/stage 2/test pipes is an amazing combo and will transform the car. I had stage 1 with the cats for about 6 months and looking back it wasn't even worth it compared to the TP's and stg2.

However, I like hearing the rev matching in each gear when I downshift hehe.

-What mileage did you install the SC? -Did you replace the rod bearings before or after SC install? -How does WOT feel in SC'd car vs. non-sc'd car? -Was the SC install done by autocouture? Cost of install?
