Hey guys I stumbled across this forum when I was looking for some info on my boss noss system. I have 2 of the 2.5 lb bottles mounted on my down tubes. In the install manual it says to mount the "Smart Box" in the airbox cover. I already have a air compressor for the Arnott air ride suspension kit so I mounted the Smart Box under my seat. Does this make a difference on the amount of power I would be getting? On the dyno I am only getting about 31-33 hp increases with 2-25hp nozzles. Your help is greatly appreciated.
