Probably a sticking throttle plate.

When they bored out your throttle body, they probably removed the plate or butterfly flap and if not put back correctly could be sticking a bit.

Or dirt in or near the throttle shaft. If the shaft binds at all the stepper motor that powers it tends to hang then overcompensates.

Re: Throttle accelerating without touching gas pedal

Had another car where that happened. Turned out that I used my self imported rubber floor mats on top of the thick carpets and that rubbed the fly by wire system in a wrong way. Maybe you have slush mats that stick?

Fastman told me to reset it. I tried it. So far so good. Johan said it has nothing to do with the tune but I did just get a new tune with my new headers and Corsa exhaust.
