I could be wrong, but most guys porting saws are looking to make them have that on off lightning fast acceleration. Even good stock saws should have good snappy acceleration, that was part of the idea behind revboost on the 550xp and 562xp. The quicker the better IMHO, I see zero negative with fast acceleration, that's what a good running saw will have. This is the first time I've ever heard anyone look at this as a negative, first time for everything.[emoji111]
