ferraris were meant to be tweaked, what do you think the entire field of motorsport exists for? from F1 all the way down to the local DE event at the local track, cars are tweaked endlessly, with passion. you won't find any shortage of tweaked exotics at your local autocross, either. if nobody "twaeked" cars, you wouldn't have ANY of the improvements in performance, safety, and comfort you find in your modern automobile.
and furthermore, a HUGE aftermarket exists for ferraris (and other cars, expensive or not) for the sole purpose of tweaking them and making them go faster, safer
there is no philosophical difference between the manufacturer "tweaking" cars, a privateer racing team putting together a specialized hill climber, or an enthusiast "tweaking" his own car in a garage while drinking six packs. none whatsoever. it's people, working on cars. period.
it's incredible there are people on HN like you. i'm a little shocked to be honest.
