Is an Accessport/tune worth it on a mostly stock VB?

This is one of the most emotionally split VB questions. On one side, a lot of owners say the Accessport plus a good tune makes the car pull harder, respond better, and feel more linear, and many specifically recommend custom or better-regarded OTS tunes over generic canned maps. On the other side, there is also a real camp of owners who say the stock VB tune is already pretty good, and that giving up warranty coverage or adding monitoring anxiety was not worth it for them. So the consensus is not “everybody should tune.” It is: the VB responds well to tuning, but the decision depends on whether you value the added power more than factory simplicity and warranty protection.
