Apologies for the lack of updates. Between work, house redecoration and other things, I've been unable to test the file - until this morning.
Up at 7am, I went to upload the file, nutski posted the link to, to the car. In short - IT WORKS! Much more noticeable turbo boost and is the car it should have been leaving the factory. The whole drive now seems completely effortless and power delivery smooth and plentiful.
With regards to the house - done the main bedroom, and the office room. Left to do are the living room, the third bedroom, the kitchen and the hallway/landing, which we are getting someone to do for us. Still, it's coming along nicely.
By the way, can anyone advise me on our construction type of the house. There's brick at the bottom (ground floor) but then it's plasterboard covered with some plastic strips for the second floor. From what I've read, it seems like it's a half-timber construction for cheapness of building it for the council (and the countless kids that surround the estate

). My question surrounds the insulation. When we bought the house, the energy ratings were quite good at over 70 for both efficiency and CO2 emissions. This sounds good, but for some reason the house seems to warm up and cool down pretty quickly. It's certainly a lot colder at night than during the day. I guess the sun hitting the plasterboard heats it up quickly. There doesn't seem to be any cavity insulation between the plasterboards.
Any advice on keeping the house temperature level?
Still got to sort out that "leak" sound from the drain upstairs, but the British Gas/Dynorod engineer hasn't showed up for the second promised ay running...
