Default Throttle body
I have a Tman 107 kit on my FLHX. I was able to acquire a hpi 55mm throttle body. I was just wondering if I would see much difference between my stock throttle body and the 55mm throttle body. I am keeping my stock injectors.

Maybe 1-3 hp and about the same torque-wise.

I'll probably put it on. I am installing a D&D fat cat so it's gonna get tuned anyways. I'm only into throttle body for about $200.00

Easy big fella. Not saying your full of ****. I just don't understand how I'd lose torque and hp. Maybe if I went with a 58mm and larger injectors the motor couldn't handle the extra air flow and fuel.
