did that bbk come with a camshaft and matching injector?

did that injector come in a black SRP box?

if yes, remove that control box, not needed.

the injector is matched to the camshaft and bbk. works perfectly fine on a stock throttle body.

only time need a fuel controller is when you go larger throttle body.
