Throttle accelerating without touching gas pedal
Anybody know what my problem would b? While at a stand still the engine revs ups and tries to go. Thank god we have the big brembo. Only thing done to my 12 is a diablo tune from Johan and a bored out throttle body and Hennessy cai

Probably a sticking throttle plate.

That's my guess too

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.

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?

Re: Throttle accelerating without touching gas pedal
drop a note to Johan about this too.

he can adjust the plate and may need to touch something/

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.
