Does anyone know how accurate the KW power gauge actually is on the mk8 GTI CS? I'm not sure whether it's a theoretical calculation or if it's really reading the power output from the ECU.
I put it on the other day, for a test, and my CS hit 300kw. Which is about right, as it hit 395bhp on the dyno after it was tuned. It did stay solid at that exact figure though, full gauge, like that was it's upper reading limit, even while revving higher.
Interested to hear anyone's experience with it.
Cheers
