I have been running an 87 octane performance tune from Brenspeed in my '06 GT 'vert. I decided to bump it up to an 89 octane performance tune (my tuner has 87,89 & 93). My butt dyno can feel the difference. :D

Bring it up and strap it on the rollers to calibrate your butt dyno.

I think its time to release the hounds and load that 93 octane tune. You'll be white knuckling it then.
