Use the VEC to pull some timing and run a lower octane tune on the highway, if you have to use lower octane.

Sunoco 260 GTX (TM) is designed for applications that need more detonation protection than street gas provides, yet cannot use tetraethyl lead (TEL). It has been shown to produce good, repeatable power levels in engines up to 12:1 compression ratio, and will tolerate more compression in engines with modern, efficient combustion chambers. 260 GTX does not contain lead or MMT. It does not harm sensors used in fuel injection systems. It is also an excellent choice where oxygenates such as ethanol are limited or banned by the engine manufacturer or sanctioning organization. 98 Octane (103 RON, 93 MON) 5 Gallon container. GROUND SHIPPING ONLY, SHIPPING CHARGES ARE ADDITIONAL, NO SHIPPING OUTSIDE CONTINENTAL USA, NO OVERNIGHT, 2 DAY OR 2 DAY SHIPPING.
