Now come to think of it should of did too. So you did feel a difference?

Different?

Yup. love it. Not sure if it's a combination that makes all the difference, but that tune brought it all together.

If you're curious about it, and in the area....

The car is WAY more responsive in either M dynamic or normal drive.

Cold day in Toronto today and the car drives much better in cold temps...

End result; worth every penny, but I would have never got it without the sale.

After my tune and after 100 miles I read your response and was thinking BS, it is better but not all what you hyped it up to be. After a week of driving and rowing through the gears I now agree with all you said. The tune was definitely worth it.

And the exhaust is different, very clean sounding; none of the roughness. My son drove it and he noticed the difference as well. It pulls hard!

In addition if the BPM or any other tune extracts more power then I'd go for it too even for 1K$.

I did this tune to my 09 and now have a 13 and definitely looking to get much more aggressive .. never did the dct tune however. are you guys seeing more crisp and faster shifts?

OP - Guessing you had this done at prestige BMW?

The DCT was well worth it way crisper shifts in all manual and M modes
Drive mode is more predictable and shifts cleaner.
The ECU flash was a nominal increase as advertised better air fuel management
I took advantage of the 50% off special but if you are looking for a lot more HP
The ECU flash isn't the one you want.

The ECU flash was a nominal increase as advertised 9hp and 8lb-ft at 6000 RPMs with better air fuel management and Cam timing.

Overall the car is running great I have the Corsa Cat back exhaust, K&N air filter
It idles smooth I can still hear the wine of the Cams over the rumble of the exhaust. I'm estimating horsepower in the range of 435 from the flash and exhaust/air filter. Next step is to get some pulleys and down pipes.
I have not had it at the track so can't comment on times yet
