Its AWESOME! Courtesy of Angel Tuning in Warickshire, a fine company I've used before on a diesel Alfa. They even came to me and did it in my garage Its sent me from 130 to 175-180 gallaping horses. I'll now have to restyle my driving, esp in the rain lol. Normal cost is a not so bad £300. Anyone thats been thinking about it - just do it! You wont be disappointed.
