A great upgrade IMHO.. Driving around shifting with ease, you'll never know there are there. But when ya really want to get on the boost in the higher RPM's ya really start to hear them puppies scream. With windows up and stereo jamming, ya wont hear them, with windows down ya can..

i received an email from chaotic s4 and he said that with his gfb valves, his miles went from 280 miles per tank to 200 miles per tank...i think this is bc it makes the car run richer

Even if it's just a little, it will cause the car to burn more fuel. It may not be enough to create black smoke, but it will affect the economy. However, it seems that the HKS may not have this problem. Unfortunately I had stalling problems with my HKS so I had to send them back so I didn't get to do a good test on them.
