e-manage ultimate will not work on your car - I have said that before. Dastek is seriously limited and will never get great results on a K11 (regardless of what anyone says - its physically impossible due to stock ecu on the K11) same for the e-manage blue.
The only way to do it RIGHT is to change the ecu for something like an Omex.
YES Its going to cost you around a grand. But that's small money if it means it can do the job properly.
I never give up my amazment for people willing to waste money away on their cars for stuff that doesnt really matter, when the real issues should be sorted first.
Let me tell you this, and also to anyone else listening. If there was one SINGLE thing that SHOULD BE done right its to sort the ecu.
You can spend all the money in the world on headgaskets, engines, bolt on bits or whatever, but it will all be nonsense if you cannot control it properly.
But will people ever listen? I doubt it.
