MateI told you already, if you dont want an expensive dyno tune, get in touch with Chris Stubbs or Vitviper, or Cullasse, they are damn good at tuning and the you will not notice the difference between a dyno tune.
It costs about £100 for a map.
Mine took, 4 revisions (standard engine.) You datalog 20 min drive and email the log to him, then he sends you a revised map, then repeat until the map is perfect.
My car is tuned exactly how i want it now. beastly. also bettermpg.
