Pre-Tuning Checklist

Pre-Tuning checklist

Below is a checklist to go through prior to your tuning appointment to ensure a smooth running tune and prevent potential problems from occurring. We begin each dyno tune with a full vehicle inspection to ensure and prevent potential problems from occurring.


  • Ensure your engine oil level is full at the time of your appointment. Bring extra oil at time of tuning, limited oil kept in stock at the shop. Low oil can bring about endless problems (including problems with VTEC engagement!). Common Honda Issues: It's common for the oil pan gasket on Honda B-series to leak. Upgraded felpro gaskets can help with that as they have upgraded metal seals where the oil pan gasket seals. It's also common for us to see turbo drain lines to leak on turbo cars. Ensure all clamps are tightened. 

  • Ensure your coolant level is full. Cars get extremely warm through the tuning process. Ensure all hoses are tightened down. Ensure the hoses are not swollen and that all bubbles are bled through. Bubbles that are stuck in the system will cause constant overheating issues. A $45 labor fee can apply if bleeding coolant is required.


  • Timing! Ensure your engine's mechanical timing is set correctly. This is pertinent to a well running vehicle & smooth tune. Check all timing marks to ensure your car is mechanically on time. We will check this during the inspection process. 

  • Check the compression of your engine. You don’t want the variance of your compression to be 20+. If your compression is lower than 20 PSI in a cylinder, recheck the compression after pouring a small amount of oil into the cylinder. If the compression increases, there is an issue with the piston rings (either not sealing or damaged). If the compression does not increase, there is a valve related issue. 

GOOD #1 155 #2 155 #3 150 #4 160

BAD #1 160 #2 160 #3 120 #4 150

  • Additionally, you will want to check the valve adjustment as well. The valve adjustment will greatly influence the compression numbers. This should be done as general maintenance as well as anytime an engine or head is rebuilt. 


  • Ensure your clutch is rated for the horsepower & torque levels you are planning to make. Certain aftermarket clutches require a break in period, please follow your manufacturers break in period prior to tuning your vehicle. 

  • Please be aware that if a clutch or transmission cannot ‘hold’ the horsepower or torque produced, you will be charged for the tune and will need to return at the retune rate. (please see services page for pricing) 


  • Ensure you don’t have any bare wires. A bare or exposed wire can easily lead to a short and endless other wiring problems!!!

  • Ensure battery voltage is between 13 and 14. Alternator issues are common due to bad alternators or poor grounding 

  • Ensure grounds are clean and bare 

  • Ensure the battery terminals are clean


  • Ensure you have the right fuel in your vehicle! Running anything less than premium can greatly greatly affect your tune. 

  • Make sure you have at least ½ tank of fuel for the tuning appointment. Running low on fuel can damage an engine during high rpm pulls. Additional fuel fees may be charged. 

Turbo Charger / Turbo Charger setup 

  • Boost leak is fairly common, most likely due to clamps not properly tightened. We recommend doing a boost leak test prior to your tuning appointment.  

  • Vacuum lines for the wastegate and blow off valve need to be installed correctly. Over boosting problems often occur due to incorrectly routed vacuum lines. 

  • 3” exhaust or larger from the turbocharger will provide the most ideal spool 


Please pay close attention to detail to your car prior to your tuning appointment.  If the problem is minor enough we may be able to resolve the issue same day. However, if the problem cannot be resolved within the day, we will have to reschedule your dyno tune. 

If your vehicle does not pass the inspection process, which means any problem the vehicle faces, will too greatly influence the tune.
