91 octane = 347 rwhp with 370lbs of torque. 100 Octane = 442 rwhp with 470 lbs of torque. Q16 = 486 rwhp with 493lbs of torque. SpecialtyZ tune and dyno the car. I can't wait to dyno the car once I replace my stock manifolds with Mike Smith. I will also upgrade the throtle bodies and intake piping. I'm hoping to get 550 rwhp then.
