Tuning Preparation

To ensure that the scheduled tuning time is spent effectively please go over the following list to make sure the vehicle is at 100% mechanical condition prior to being tuned.  Calibration is very hard on engines and drivelines and will push the vehicle to ensure that the components are calibrated correctly and safely for all operating conditions. Pre-existing mechanical problems will result in an inaccurate and potentially unsafe tune and can potentially result in catastrophic engine or driveline failure in extreme cases.


  • Engine Compression tested and within spec and no more than 20psi variance between cylinders

  • Cylinders leak down tested with no more than 7% leakdown

  • Intake manifold and any associated intake piping sealed under vacuum

  • Exhaust tightened and leak free

Preferably no open headers due to noise and sensor inaccuracy, at least 18”-21” of piping required after header primaries if open header

  • No leaks from crankcase, cooling system, transmission etc.

  • New Spark Plugs with correct heat range for application

          Please contact me for correct plug and heat range
