was thinking of trying out Eurocharged as they are local here (Houston).. my CTT-S is stock (well.. have fabspeed cat pipes, and updated aluminum coolant pipes minus the t-connector -- long story <sigh>, that's it).. do i need to update the diverted valves? anything else to update? would it improve the gas mileage? would just do some spirited driving but mostly the car is for daily driving..

thanks for your input in advance.

 

If you are going to add a tune, I would definitely recommend a DV upgrade- they go hand-and-hand. Aftermarket tunes tend to have higher boost pressure which might rupture the stock DV diaphragm with enough time. The aftermarket DV will also allow you to hold more boost and prevent leaking.

Another cheap and good add-on would be either upgraded air filters (BMC, KN) or aftermarket air intake. The tune will perform best with upgraded DVs, Intake, Cat Bypass, and Exhaust.

That should be pretty much all you need.

Moreover, I haven't heard of anyone running that tune.

 

I run a Eurocharged tune in my 04 CTT. I also did the DVs prior to the tune just to ensure no issues with the increased boost. I'm on my second tune with them for my cayenne. The first made a lot of power, but it came on like a light switch. I had Jerry retune it for a smoother power delivery and it's much more to my liking - there was no charge for the change. I've run it with both the EVOMS intake kit and with the stock airboxes with no difference in driveability.

I also run the Eurocharged tune in my SL65 without issue.

 

I have a eurocharged tune on mine, waiting for my revised one right now, Jerry is great to work with, no problems to speak of... upgrade the DV's if you want to up the boost though
