Picked one up today from DTUK (the tri channel model), after speaking to them on the phone yesterday I had a few questions/reservations regarding the tuning boxes, he soon put them to bed and I promptly decided to drive up today to pick one up.
Dealt with Simon who was very knowledgeable and he fitted the unit for me (5min job), and then spent the next half hour out on the road with me trying the different settings and explaining how it works.
I preferred map 3+2 as in my opinion it has transformed the car completely, it pulls better all round, and feels smoother for some reason,and when you get past 3k it really comes to life, they claim around 240ps and I wouldn't be surprised if it was,as it feels way way quicker than before especially in the higher gears!only done 200miles but so far very happy with it and would recommend to anybody thinking about it. Too early to see any difference in mpg yet as Obviously i needed to ensure the box was still working,,in every gear, all the way home.
