Also, don't newer cars like 182s, probably 172s as well have 'learning' ECUs? You drive like a granny all the time and it sort of 'adapts' to your driving and sort of goes more 'economy' ? This might not be true, but I'm sure it is - although whether it makes any difference to actual power is surely unlikely?
My mate always used to say, when he drove his GF's C2 GT like, to town and back, he'd be twatting it on the way there (she drives like a granny) and saying it felt sluggish and slow. Then after the thrashing, he'd drive it home the same way and always said it felt much quicker!
Although, to Crabbo182, as you say you give it some often anyway, it doesn't seem like this would be an issue heh!
