Looks identical (including figures quoted on their website) to this one : TMC Motorsport - Car Products - which I've had fitted to mine for 4 months now and boy, does it make a difference to the already pretty impressive mid-range performance, . When you drive normally, it even improves fuel economy by about 10%, . When I had to remove it temporarily for a visit to the dealer (warranty repair to the suspension) I thought that the handbrake was stuck on, it felt so sluggish by comparison.

Clutch is probably only an issue if you like slugging with it

Agreed. With the increased torque, trying to boot it away from a standstill has the traction control light flashing like a distress beacon and the steering wheel squirming as the differential tries to sort it all out, .

So I tend to pull away in 'sensible' mode then above 30mph (50kph) plant the right foot at which point it accelerates like a fighter-jet on reheat, . I've given some pretty 'meaty' motors a big fright with that when I suddenly launch towards the horizon, .

159 tbi Ti

Installed my box a couple of days ago. Decreased mpg with 15% or so driving long distance slowish. Pulls really great from 2000 rpm. I will put it the dyno and compare some acceleration values soon, though, to get some hard data. No probs as u describe. Very easy install.
Cheers
Peter
