Default Do I Need Tune For larger Throttle body??

Well i craked th stock PI lower intake mannifold and im forced to buy a new. And i figured it to be a good time to upgrade in the process.
Im looking to get a packedge deal consisting of an Upper Plenum Kit, Throttle Body (70-75mm), and a Typhoon lower Intake.
Well my question is if i get this will it need a tune to be effective. Will the car run good without the Tune? Thx for your help.

You'll be fine without a tune.

Its not that big of a change from stock so no tune required but would help.

The car will run fine without a new tune. But you will benefit from a tune over the stoc one for sure.
