I'm running the 93 octane tune from Brenspeed,......excellent customer service. Brent explained that with 93 octane the engine can make more torque, at lower rpms,.....less reving necessary for same exceleration. Potential savings if you can keep ur foot out of it.(not possible)
Also it is nice for the knock sensor not having to constantly retard timing to make up for weak gas......to me 93 is the only way to go. Now if you are just burning gas on a highway comute......then the 87 tune would be the way to go.
