Good evening 
Arrived nice and early after getting up at 5.30am and cruising along the M5, M42 and M40 - slowish drive (60 - 70) as I tend to drive slower when tired. DIS said 62mpg average for the trip.
On the drive back at 80-90 (and some faster blats!) 57.8mpg per DIS, not bad at all after my much faster drive home, and the fact that I had the car running in the services for about ten minutes with the heater on.
pre-map figures were 78.3 bhp at 3673rpm and torque 164.4 at 2354 rpm
Post-map figures are 101.7 bhp at 3149 and torque 208.1 at 2218 rpm
Vince thinks that my power figure is being held back by a very dirty air filter as the car struggled to maintain power to the redline - on the basis that no fault codes were identified and all else was well. He didn't have one in stock unfortuntely, so we couldn't change it.
It doesn't drop away rapidly or anything, but the graph indicates a potential breathing issue at the high end of the RPM scale. I thought about changing the air filter before today but didn't find the time. Good news though is that a new air filter should make the car better still, maybe another 6/7 bhp and hold the power a bit longer.
In terms of the new driving experience, the car feels much more flexible throughout the rev range and the motorway performance, particularly between 70 and 100(+) in 5th gear is massively improved. I think the relatively low weight and the slippery aerodynamics of the car really help at these speeds, which is why a 'relatively' modest increase in torque makes such a hell of a difference on the road.
I don't want to give anyone thinking about having this done unrealistic expectations, this won't turn your little beastie into a 'Type R baiter' from a standing start - I would guestimate a second, maybe more off the 0 - 60 time though. What it will do is transform the car big time in terms of 'in gear' acceleration, particularly at motorway speeds. It also makes the engine much more flexible - all in all thoroughly recommended, and an absolute bargain at £225 +vat.
Obviously, loads of peeps on here been stealthed already, but just wanted to add my honest thoughts for those thinking about it - DO IT !
Big thank you to Vince and his crew !!!
