I would like to know the same thing. Losing Exhaust note doesnt really bother me but a de-tune does. A dyno run between the 2 would be a great comparison...
I want to do something though because the hesitation drives me nuts and is potentially very dangerous especially if it's raining. I may have the dealer do this when it's in for the battery cable recall. Mt wife's RSX is more predictable than my 1er when pulling away from a stop...just aint right..lol
