What’s Included:

Important Notes on Installation:

• Calibration Required:
  Custom tuning is necessary to operate the upgraded pumps safely and effectively. Do not run the engine on stock calibration with these pumps installed. Spool Performance provides tuning data to your existing tuner and can recommend experienced partners if needed.

• Low Pressure Fueling Support:
  Ensure your low-pressure fuel system is upgraded accordingly. Inadequate low-pressure fuel can result in internal pump damage due to lubrication failure, which is detectable and will void warranty coverage.
