I understad where ya are coming from with the noise and reving issue. But the thing is the rotary is a engine you gotta keep revving to see if everything is working fine in it. Gotta see if the nitrous system is activating how it is suppose too, Gotta hear if its mixing right and cleaning out how its suposse. So they have their reasons for revving so much. Thats how you are suppose to tune them,Its is funny cause alot of ppl that complain about the rotarys are the ones that dont know jack shit about them.
