with the intake stuff here, we're using much lower velocities & i would think it would matter a lot less. what do you think is reasonable? 1X the tube diameter?
The problem is, it has to match the 996. If they dialed it in near a bend or filter, you have to do the same thing. And be in the same relative location to the bend with regards to the circumference of the tube. So it's not a matter of you picking a good spot to start from, it's you having to pick the same spot that the ECU expects.
