Search any number of forums mate and you'll have your answer (HTUK, Falkirkcruise, VAG Owners etc....). Everyones cars were down around 40bhp, even my mates standard Hawkeye STI was given 240bhp reading at hypertech and was ment to be doing well at that according to them, he then took it to Extreme and it was just shy of 300bhp with no changes made to the car. I could list more similar examples if your interested.
