Your engine will make more power and torque with 100 octane fuel and a professional tune. The downside is you must always use 100 octane fuel with that specific tune. You can use lesser grades of fuel if you use a map-switching device such as the Cobb AccessPORT, but performance will be correspondingly less.
Do NOT try to use a 100-octane tune with typical pump premium (91 or 92 octane). Your engine may suffer severe damage from overadvanced ignition timing and higher turbo boost settings.
