Anyone using ECS RACE N75 Valve? Are their claims true?
A friend came across this and sent it to me. I a little skeptical, anyone use this setup or have any impressions?
The Power: The N75 is the VW/Audi part identification number for the wastegate by-pass regulator valve. This valve is responsible for controlling the movement of the pneumatic actuator which drives the wastegate. The wastegate is an internal valve in the turbo-charger which controls the amount of exhaust gas that flows over the turbo impeller generating boost. Under normal operating conditions the engine's ECU sends signals to the N75 valve asking it to open or close which adds or reduces pressure on the wastegate actuator which results in more or less boost. The ECS RACE N75 valve modifies the normal operating parameters of the original N75 valve by delaying the speed at which these ECU signals are interpreted. The result is a higher initial peak boost and an elevated boost curve which tapers back to stock/chipped levels over the engines rev range. Average boost gains are 1-3psi over the rev band.
The Positive Side Effects: As discussed above, the ECS RACE N75 slows the speed at which the wastegate reacts to ECU boost control signals. The result is a smoother boost curve. Many customers who had "jerky" power curves found that not only has the RACE N75 valve added extra horsepower, but has nearly eliminated any irregularities in their engines power curve.

What you need to do is ditch the N75 all together and run a boost controller.
Then you'll be able to make the boost do whatever you want. Personally I wouldn't buy the modified N75.. Most chipped cars make enough boost for K03s already. As for "smoothing it out", that just means less boost at lower rpms... =T

It's basically just a slower valve so you'll see higher boost.
If you're not chipped this is not a real big problem, but if you are I really don't recommend it because you're probably already making more than enough boost.
