I did the TPS recalibration yesterday, and leaned it out.
It feels like a different car. the power delivery's much smoother, and it feels like i've gained about 30-40 bhp. when blatting 1st and 2nd, it feels like the car's trying to do a wheelie!
Before the power kicked in very noticably at 5k, now it seems to be less on/off, and starts at 3k and just grows and grows.... and the best bit is that it now uses less fuel!
Bring on the rolling road day.
