996 TT X50 with a GT2 MkII software ?


Recommended Posts


I own a 2003 X50.

Some say that the 2005 turbo S has the same power output as the mkII gt2 483bhp (but they still don't have the same clutch and transmission right ?).

Since the engine of the 2003 x50 shoud be the same as the turbo S, is it possible the flash the ecu with the Gt2 file to get those 33 missing bhp ?

Thank you.

There are several flashes available which would be better than the GT2 map and get you significantly more power.

Agreed! If you are going to flash it, go for some real HP! There are a number of them available. I have Softronic 93 Octane tune for my 997 TT and love it!

Good luck....

Lots of companies out there for flashes. If I were to flash mine I would go with Kevin at UMW or Markski at 911 Tuning (Protomotive tune). My car came with a GIAC tune through Champion Motorsports. They updated it for me at no charge and I am pretty happy with it. I'm very happy with their customer service!

Kevin at UMW is a fountain of knowledge and will go through a litany of options for you to choose from. Just have some time to talk with him ... Like I said, lots of knowledge.

I see you are in Switzerland, yes?

The advice I always give people is this: WHO will be doing your work? your maintenance/upgrades? Your TROUBLESHOOTING? You will want to choose a tune that THEY are comfortable with...

Or chose a tune where the tune company is willing to talk with your shop and answer their questions.

I used UMW.... but Marek, todd would all be fine I suspect. I am actually not too familiar with EU-based offerings...


PS The GT2 exhaust is slightly different- so some of that power may be due to sightly reduced backpressure. DO consider a new exhaust, power AND better sound. Europipe is made in belgium, one of the best.
