I've had mine done, it still needs some work though I feel, mine hesitates briefly at 4K if you come off the throttle then reapply it don't recall that before but maybe I'm being critical and after adjustment the throttle response was set to 9 (I think), talk about hair trigger, made it very difficult to be smooth, now set to 5, still great response seems to have an extra edge to the exhaust note too,
definitely revs longer almost as if rev limit is raised, I think it actually just gives that extra 10-15% rather than any extra revs to get a little more speed in each gear. I am waiting to get it rolling road mapped using the Revo map to see if I can get rid of the 4K hesitation
ignore next bit for any speed phobes...
my Sat Nav shows max speed attained as 153... although over 100 my speedo reads 10mph over the Sat Nav so at that point it was off the clock, it didn't do that before, pretty much hit a wall at indicated 155, no not in UK but easy to get very illegal with the 3.2 with almost no effort.
