Anyone de-airdoser'd their HDI?

[rryan]

i removed my inlet elbow to fit my boost gauge take off and at the same time i removed the butterfly part of the air doser, but i havent notched any difference , so its probably not worth swapping over. (im not sure whether the non air doser inlet elbow flows better)

it is worth cleaning the sooty crap out of one of them tho
