Air filter Question
Been doing some research and I was wondering if its necessary to get an ecm calibration when you change to a large volume air filter such as a screaming eagle stage one or a heavy brather? This woulb be for an 07 Street Bob. Also would a Vance and Hines fuel pack be all that I would need ?

It would be a good idea.
Yes, the V&H fuelpack is one way.... and if you only change the air intake, it would probably suffice. Anything else, like new exhaust pipes, and you'll want a remap or a tuner, which is more convenient that a just a remap by the moco.

If you change the air cleaner to a high flow one (SE Stage 1) you are increasing the air volume to an already lean engine condition - so YES, you would need to have some fuel management to richen up the mixture. The V&H FuelPak would be fine if you do not intend to make any engine modifications that would require more complex fuel management. I"ve used the FuelPak and the SE Stage 1 air cleaner and the V&H Straightshot Slipons for over 10,000 miles and everything runs fine.
