A larger throttle body doesn't necessarily mean more horsepower. You can actually ruin a good thing with too large a throttle body unless you have a complimenting engine build. What do you have for a build?
Save your money....a larger TB won't do a thing except disappoint you.
A larger TB probably would give him a few more peak ponies, at the cost of low end tq. On and Ultra Classic though? Why you would want HP is beyond me. If it were mine I would be trying to get that TQ curve up. Bigger cylinders/pistons and some minor headwork would get you going. Probably would be close to the 5-$600 range you would spend on a TB. I personally think theres much better cam options than the SE also. But you already got em so what the heck.

The stock TB is capable of flowing whatever stock heads and a 255 cam can manage. It won't do anything except waste his money.
