Octane boost

Do the vQ37 engines benefit from 98-100 octane fuel without a tune?

Use high test fuel that is readily available at the pump.

Unless you've modified the engine by increasing the compression, all the octane boost in the world won't make a shred of difference to the performance of the car. Higher octane is required only to prevent premature ignition under compression.
