Fuel

Be sure to run highest octane available at your pumps! This is critical for a forced-induction vehicle. If most of your tank is full of a lower octane fuel, postpone your install until you can fill up with the right stuff.

Tips to ensure best performance:

  1. If the existing is old, replace your cap, rotor, and spark plug wires.
  2. Use spark plugs 1 heat range colder, and gap at .029-.031
  3. Upgrade to 4-hole injectors.
