You will definitely need a tune.

I would also be surprised if you do not need larger than stock fuel injectors with that setup too.

Nope, the computer does not learn wide open throttle only part throttle.

And even then, you still want to tune it because it's not going to learn everything. You're going to have a tough time driving an untuned car even on the street.

Full tune is required.
