I used one on my 182. Don't expect any huge gains in BHP, it improves what Henk mentioned in his post, generally gives a better driving experience. I found it smoothed out the power delivery on mine, the car didn't have the 'kick' at 5500rpm, but felt a lot better to drive. I bought mine second hand from here (You'll need to become a club member to access the for sale part of the forum). Fastchip always seemed to be out of stock. It cost me around £95 for the tuner, I then bought a reprogramming license from Fastchip so I could tune my car, this was 50 euro's. It was really easy to use, download the software, connect the tuner up to the car and connect the other end to a laptop. I had the car mapped and up and running in no time.
