BD Engineering did a superb job on my mk5 Escort 1.3 fitting the K&N filter and tuning her up........
The Land Rover Disco 3.5 V8 we had, had numerous problems with running rich and missfiring...........they never found a problem with it even though it was 100% guaranteed there was one.........
In the end he took it one day and drove it for 10 miles........on coming back and us collecting it he said there was no problem with it and running really nice and clean.........he didn't charge us and sent us away.......
Turns out a few weeks later that the battery died and when we went to replace it........the battery had broken down and the plates were bobbing about and causing the missfire.....
the overfuelling was never solved as earlier this year it got a little dented
Back on topic..........good to know a rough idea of power figures dude as always.........but as far as I am concerned if you enjoy the car and feel it is powerfull enough as you want it to be then thats perfect
