• Pre-Tuning Info

  • Car must be mechanically reliable, and ready for a tune. I will not install parts on, or fix your car for you. If you need parts installed, we can work out something before we schedule tuning.
    • Tuning will not proceed if car needs mechanical attention before or during tuning.
  • Recommended you have extra oil, extra coolant, and extra set of spark plugs on reserve.
  • You must have a wideband Air/Fuel meter gauge for any tune.
    • The reason being is that proper air/fuel mixture is required for safe & reliable running of your motor. I will not willingly tune a car without being able to adjust the tune to these readings.
  • Stock Honda injectors only good for up to about 5 psi/lbs of forced induction. Stock Honda map sensor good for about 10 psi/lbs. Upgrade your injectors/map sensor if you want more.
  • Must have a version of Hondata s300 (v1, v2, or v3 acceptable).
    • Otherwise will consider tuning chips if you have all the hardware on hand (chips, chip burner, software, cables, etc.)
