New carbs??..

Never messed with a tunnel ram. If you’ve got things dialed in pretty good, and you understand the eddy style I say stick with what you know. As stated I’d pick up one to match one of the other two. My gut says that even if you bought 2 of the exact brand p/n etc there will be variances just due to manufacturing tolerances. Me I’m kind of simple and like to stick with what I know. Isn’t the quest to perfect the little nuances fun.
