Maybe with some electronic you see better results. A bigger throttle body only gives you better results with bigger Turbos.
Possibly but I'm sorry but a larger TB provides much more air and better throttle response. These are just two of the benefits of a larger TB. I have a much larger throttle body and far better throttle response and torque with the OEM turbo. What accomplished with a larger throttle body, is far more intake air and CFM that enters the cylinders. Add both intake manifold and TB spacers and you get much better air equalization to the cylinder and a smoother air flow.

With a larger TB there are appreciable gains in hp up to and beyond 10 whp.

@Bu11eT you're knocking on the door of 300. You tuner is correct, a tune is needed to realize the full capability of the bolt ons.
