Ha don't mistake my disagreeing with you for a lack of understanding. Who said anything about top end? If you overlay the two AFR lines either there will be places where the twin intakes have caused a lean situation, or there won't. I'm not making a definitive argument either way, I'm asking for somebody to SHOW me. Too much from one mod? The whole conversation has been in response to people saying "yes go twin AFM it's a breather mod". I expect NOTHING, I am however happy to be proved wrong in the event that someone can show me SOMETHING. I keep reading about how I should see a change in AFRs OR a change in power/torque/response with back to back testing, perhaps I expect too much in asking someone to demonstrate this? Ocham would have a field day
