No 1 is a re-map. Your car has a 'brain' called an ECU. As this leaves the factory it is designed to be all things to all men and has certain tollerances built in - be average at everything but exel at nothing. It will always be possible to gain more power or more economy, or both, from a 'factory standard' ECU by a simple re-programming of how that brain thinks (variations to fuel/air mix at given RPM - I could go on but it gets quite technical).
These come in two forms: 1) a basic 'plug and play' which will be a standard map previously created for your type of car, but not specifically 'your' car. 2) a custom re-map, which'll involve your car spending a few hours on a rolling road to have the new map created specifically for your engine and your desired requirements.
Plug n play will be cheaper but yield lesser results, your looking at approx £300 or £500 for each respectively. My advice, do your research, a bad map will do more harm than good - beware cowboy tradesman doing it on the cheap. Expect anything from 10-25% more spunk for your money.
Next stage is to alter the cars ability to 'breathe'. As above, as a standard car it'll be held back to meet 'standardisation'. But, allowing the air to enter and exit your engine more freely will again result in more power. Budget £100 for taking the air in and £300+ (up to £1k) for air out (exhaust) modification. Expect anything from 2-15% more spunk for your money. These modifications will make certain engine characteristics louder - some see this as a good or even great thing. I don't recommend 'boomy' exhausts, they draw too much attention to you when giving it a boot-full.
Anything after that your being more serious and involving more £'s, although I can elaborate if required...
If planning on doing both, sort the breathing before a custom map, or the 'custom' bit will be outdated by the new ability to breathe. If going with 'off the shelf' map, don't change the breathing as it'll not be set up to take advantage of the improved breathing ability.
I've actually met Chris n shook his hand. This fact is still causing slight issues in my trouser dept....
