mine was dyno at 150 hp and 152 torque they did put aluminum behind my K@N filters they say that it helps from all the heat off the engine so it could breath more cool air they told me that they find it gives you more hp and torque that's why I think they got the best out of my Rocket.
And now this other guy is saying he could get 160 - 170 , but you can only do it with Tuneboy is there any one out there that could back this up? I would just like to see if this is possible I hate to put out money to have him perhapes mess my set up I have now.
