It's early days i know... and i'm the first to admit this is the 1st time i've had any of my cars re-mapped, so i really didn't know what to expect in gains... But i must admit i was surprised at just how much extra power (and more importantly) torque i'm feeling... I'm a bit of a plodder at driving 99% of the time, but every once in a while i do like to stretch the old legs of the focus... pre-mapping, i'd get a visible fair old puff of black smoke on the slip road to the M6 when i gunned it in 4th then 5th... That now seems to have completely dissapeared.
And another unexpected benefit... My car (in fact, every diesel i've ever owned) sounded, and felt lumpy on a cold start, that would gradually fade as the engine warmed... each morning since the mapping, as soon as i've pulled from the drive, the engine would behave as if it was warm! Not only sounding smoother, but felt smoother too! How's that work?
Injection timimg, fuel delivery, air flow, etc etc etc... will all affect how the car runs, as all this is changed that could well be the reason why it feels smoother etc from cold.

Out of interest who did you use to remap the car?
Be careful if putting your foot down in higher gears at lower speed, this would result in clutch slip and fly-wheel vibrations - too much of this will cause damage!!
Perhaps feeling smoother as the fuel delivery will have changed.
Have you had the car rolling roaded to see the actual BHP?
If clutch and flywheel are in good nick you should be fine, as has been previously stated, if you can afford it, go single mass or uprated dual mass flywheel, and depending on what future plans are, uprate the clutch... saves bother later on!
