Pre Dyno Tuning Checklist

Pre Dyno Tuning Checklist

To get the most out of your tune, go through the following list prior to your dyno tune appointment. This helps ensure you get to drive your car out of here, safer with less problems, with less headaches and more horsepower.

We assess each car prior to being ran on the dynomometer. We begin each dyno tune which includes but is not limited to a compression test, fluid checks, suspension, tire assessment and more. Our dyno is a 2WD dyncom dyno.

Here is a list of assessments you can make to ensure a smooth dyno appointment. 

#1 Fluids

  • Ensure your oil is topped off. Bring extra oil at time of tuning, limited oil kept in stock at the shop and extra charges apply. 

  • Ensure your coolant is topped off. Cars get extremely warm through the tuning process. This is something to ensure at all times, especially with a modified vehicle. Ensure all radiator hoses are securely on & tightened. Ensure the coolant hoses are not swollen. Ensure that all air bubbles are bled through if any part of coolant system has been recently replaced. Bubbles that are stuck in the system will cause random but consistent overheating issues. A $45 labor fee can apply if bleeding coolant is required.

  • Top off transmission fluid. Being low on transmission fluid can prematurely wear your transmission synchros & gears. Ensure your transmission fluid is topped off especially if you have an active leak. Limited transmission fluid kept in stock.

#2 - Engine 

  • Timing! Set your engine timing. 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. If you are using aftermarket cams, it may be required to degree the cams to ensure the car is on time. 

  • Check the compression of your engine. You don’t want a variance greater than 15%. If your compression varies more than 15%, 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

  • Get a valve adjustment. This will optimize your horsepower and compression. This should be done as general maintenance as well as anytime an engine or head is rebuilt. 



  • Check the specs of your clutch. Ensure your clutch is rated for the horsepower & torque levels you are planning to make. If you have a turbo'd vehicle, a stock clutch will not hold. 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) 


  • Clean all bare wires, engine grounds and battery terminals. A bare or exposed wire can easily lead to a short and endless other wiring problems! Your tune will not run optimally if there are electrical problems. Cleaning the terminals and battery grounds will help ensure that all sensors are receiving a healthy voltage. 

  • Get your battery and alternator tested. A tune is dependent on a battery's voltage reading. Thus ensuring your battery voltage is between 13 and 14 is pertinent to a healthy tune. Alternator issues are common due to bad alternators or poor grounding 


  • Come with 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. 

  • Change Fuel Filter & clean fuel injectors. It is common for fuel systems to collect dirt and debris. Ensuring this system is clean improves a tune dramatically. It is common for a faulty fuel system to prevent an optimal tune. 

Turbo Charger / Turbo Charger setup 

  • Boost leaks are fairly common, most likely due to clamps not properly tightened. We recommend doing a boost leak test prior to your tuning appointment. If you do not have a boost leak test, tighten all boost couplers and clamps as needed. 

  • 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.
