JCW and Tuner File is Excellent. JCW, Special Tuner file, and Manifold is ...
AMAZING!
I have been running the Tuner file for the last two months, and I cannot believe the difference in the car and that people would contemplate replacing it with the old file because there is a "flat spot". There was only one direction...more.
I have now added the special tuner file and the manifold and it is awesome. It totally transforms the sound of the JCW. It is not only louder, but more importantly it is meaner. There is a big difference in both torque and power (or are those the same things).
The only other mod I have is the GRS Intercooler, which is also very good.
Any JCW's out there, I would not hesitate to do this. The difference is dramatic and like the intercooler is fairly quick to remove before heading to the dealer.
Also, great service from Volker.

I will be doing the tuner file with Tradiuz soon. We will Dyno my bone stock (well JCW) 05 before the file... drive it for 100 miles that day and then dyno again... hope to have numbers soon!
Stay tuned!
Stay tuned!

I am an American actually living in Spain and working in London. The car is in Spain. I don't believe they do a smog test until the car is 3 or 4 years old.

Joel, I'll let the Volker confirm this, but I read a post from him in another thread that the odometer reset will not accomplish what he wants. He recommends a full reset (my words, not his) at the dealer. If I can find the comment, I'll link it.

Are there any more JCW owners with experience with this tune? It sounds very intriguing, but I would like some more stories/experiences from users if they are out there. Dyno's would be even more helpful, but that's a lot to ask...

My experience has been that about 3 tanks of gas are enough to allow the "other" ECU cache that the speedo reset doesn't clear to adapt. I've never explored asking the dealer what they would charge to clear the cache (and am hesitant to do so).

Can´t wait to hear the owners about it!

Do you have any dyno plots illustrating this 400-500 mile need for adaptation?

The Europeans use the term 'manifold' to refer to what we call a 'header'. I'm pretty sure in this case that the poster was referring to the tuner file/header combo from MTH. Or I could be all wet!
