well thats why i asked the question... lol to find out what peoples views are? as im not the most clued in!!! as uv exposed lol!!! haha either way it seems not many people have got involved in this topic.. which looks like to me that not many people have gone for engine mangment recently. (or just cant be botherd...lol) ie gotech or something along the lines of that. then i could find out how the characteristics of the car changed after the mangment was fitted. it must make a difference to the way the cars drives and responds and the power delivery.....
