Pre-Tune Checklist

Tuning DOES NOT fix mechanical issues or misfires. Tuning is designed for vehicles that are already in good running condition and designed to make aftermarket parts work properly together.

If you feel your car has any mechanical issues or is misfiring please contact us and we can schedule a time before your dyno tune and fix any problems it has. If we strap the car on the dyno and find misfires or other issues we will charge you the dyno rate of $225 an hour to repair the issues or remove the car from the dyno and reschedule your tune and charge you for the time on the dyno.

Checklist:

  • Make sure you have the fuel you want to be tuned on in your vehicle when you come in for the tune. We can only tune your car for the fuel that is in the fuel tank. If you tune on 93 octane you will make more hp but you can damage your engine if you boost with 91 or 92 octane in your vehicle. If you want to be able to run 91, 92, or 93 then you will want to tune your vehicle with 91 octane in it.
  • It is recommended to NOT run 91 non oxy or non ethanol (see images below for examples). We have found turbocharged Subarus do not like this fuel and it acts like a much lower octane in real life testing. We will tune your car on that fuel and you will make substantially less hp. If you decide to come back with a better fuel you will have to pay for a tune adjustment (dyno hourly rate). If you do need to be tuned on 91 non oxy we have found an aftermarket intercooler helps keep the power where it’s supposed to be.
  • Perform a compression test (knowing the health of your engine before the dyno tune is critical to make sure you get the most out of your tune. Compression should be within 10% on all cylinders.)
  • If tuning 02-14 WRX/04-07 STI models for over 22 PSI an aftermarket MAP (manifold absolute pressure) sensor is required
  • If tuning 08-Current STI models for over 26 PSI an aftermarket MAP (manifold absolute pressure) sensor is required
  • We CANNOT tune with misfires or a bad front O2 sensor (vehicle AFR sensor)
  • Verify front 02 sensor is in working condition (we DO NOT recommend using aftermarket O2 sensors, even if it’s the same brand as the OEM they can read differently then stock and typically don’t last as long. Always buy OEM from the dealer)
  • If you don’t know the history of your spark plugs please replace them beforehand (if your car misfires from bad or improperly gapped spark plugs on the dyno we can not complete the tune until that issue is resolved. We can replace spark plugs/ coil packs on the dyno at the dyno rate of $225 an hour, plus the cost of the parts.)
  • Clean your MAF (mass air flow) sensor with MAF cleaner (we DO NOT recommend using aftermarket MAF sensors, even if it’s the same brand as the OEM they can read differently then stock and typically don’t last as long. Always buy OEM from the dealer)
  • Verify no boost/vacuum leaks. If you installed a front mount intercooler or had your engine apart a boost/vacuum leak test is a must
  • Clean or replace your air filter
  • Check or replace your fuel filter
  • No exhaust leaks
  • No oil/coolant/transmission fluid leaks.
  • Fresh engine oil to help prevent engine failure at higher RPMS. (Mobil 1 and Royal Purple are NOT recommended in turbo Subaru engines. For the EJ engines, we recommend Rotell T6 5w40, Motul 8100 X-cess 5w40, Motul 6100 Synergie 10w40 (good for E85), or Motul 300v 5w40, 15w50. For the FA’s we recommend Motul 8100 X-clean efe 5w30 ).
  • For Single fuel tunes please come in with at least 1/4th tank of gas.
  • For Dual Fuel/ Flex Fuel tunes please come in with at least 1/4th tank of gas but no more than half. No need to bring E85 as we supply it and the price is included in the flex fuel tune.
  • Clean out passenger seat
  • Make sure tires are fully inflated to the correct pressure (30-40psi recommend)
  • Your car should have a proper wheel alignment (if it pulls hard to one side we can not tune your car)
  • Make sure your clutch is not slipping and able to handle the torque for the upgraded mods
  • Make sure your battery and charging system are operating properly
  • Vehicle must be road ready
  • No large group of friends.
  • If you have air ride please have the car raised as high as it can go
  • If you have a front splitter or rear diffuser please have them removed so we can strap the car down. As long as the rear diffuser doesn’t block access to the lower control arms it can stay installed.
  • Vehicle must have a minimum ground clearance of 3.5″
  • Vehicle must have normal street tires (summer or winter tires are fine). Radials and slicks do not work on our dyno

We do offer pre-tune inspections (Call for vehicle pricing)

Our pre-tune inspections can include:

  • Compression test / replace spark plugs
  • Boost leak test
  • Fuel pressure test
  • Clean MAF
  • Test front Oxygen Sensor
