  • The Included LS controller package is for engine control only. Does not contain any transmission or body control. The ECU comes with calibration that is optimal for our engine, however, please note that vehicle parameters such as gearing, tire size, vehicle weight, air intake, headers, etc. may necessitate additional tuning once installed into your specific vehicle. The included ECU is unlocked for further refinement at your local dyno shop if required.
  • BluePrint Engines recommends Air Intake Kit BPPLS01013 to ensure correct MAF calculations and Dyno calibration are maintained with the provided ECU / tuning.
