Installed on a 2011 xwd, install was very straight forward, took about 45 minutes. The difference can't be overstated. Sounds phenomenal, quicker response, all but eliminates the lag. Expected i would only notice the blow off when driving in manual mode, but there is no missing the woosh as you throttle up and the simulated blow off when you release. I'm guessing the first week or so MPGs may suffer as i don't think i can keep out of the turbo. It's just too bad the winter is coming so soon, I just want to drive with the windows down for a while ad enjoy that sweet sound
