Default Throttle Body question
When upgrading to a 128 big bore kit, at what point should a throttle body upgrade be included? I am not shooting for max numbers at all. More for ride/reliability than how much I can wind it past 6k. Ideally I would like to stay in the 130hp/140tq range. Right now, I have the kit, cam (and all that goes with it), injectors, and manifold in my cart.

Thanks!

Only really needed if you go Stage IV with better-flowing heads.
