ALL VEHICLES tuned by PRE must retain the following Emission Control Components: (Catalytic Converters, Air pumps, EVAP, PCV, & EGR.)

We will tune dedicated race cars without these "Emission Control Components" but the car must arrive and leave by a trailer and NOT be registered for street use. If you have questions about whether your car meets these criteria, contact us. TO BE CLEAR, the vehicle MUST be a dedicated race car, if we deem it is not, we will not tune!

FREQUENTLY ASKED QUESTIONS

What do need to do before I bring my car in for a tune?

The Dynamometer simulates road conditions and is no harder on your car than what you will encounter naturally on the street. The only reason a car will ever blow up on the dyno is from a mechanical failure. The reason for the failure can be many things but it is never from the dyno itself. In over 320,000 dyno runs logged on our Dyno, there has been about a 0.002% rate of major mechanical failure.

Should I worry about Air Leaks?

The number one thing we fight when tuning cars is air/vacuum/boost leaks. Before bringing your car in for a tuning appointment be sure that all vacuum lines are tight and in good condition. Performance Race Engineering can do a simple smoke test that pressurizes your entire intake/PCV system with penetrating smoke that will aid in finding any leaks. Once any leaks are corrected tuning can begin.

What do I need to know about my Spark Plugs?

Spark plugs are another often overlooked item when tuning a car. Plugs are the final step in the combustion process and are ultimately what decides if you get full combustion. We recommend the NGK or Denso Iridium spark plugs for all cars we tune. Be sure to check your vehicle-specific application guide to see what plug and what temperature range you need for your car. Remember that the factory plug gap is designed to run a factory car. Chances are if you are tuning your car it is no longer a factory so be sure to gap your plugs accordingly. The typical gap for a car running 15psi is .030in cars running higher boost levels may require gaps down to as low as .015in. Ignition system upgrades will allow you to open the spark gap up more but that is an entirely different discussion. We carry NGK Iridium and Denso Iridium plugs in stock for most common applications we tune and we can install them for you prior to your tuning appointment.

Is fuel quality something I should consider before a tune?

Fuel quality is very important when tuning a car. Always bring your car to the dyno with the exact fuel mixture you plan to run. If you usually buy your gas in Oregon at a Chevron next to your house it only makes sense to tune the car on that gas. In general, try to pick a fuel station that has separate pump nozzles for each octane fuel they sell. This will help you get the most consistent fuel in your vehicle. In general, we recommend our customers stay away from any fuel additives or octane boosters. Fuel consumption will vary depending on your car's fuel delivery system, overall horsepower, and tuning time so be sure to fill your tank before bringing the car in for a tune.

What type of tires should I use when tuning?

Tires are also important from a safety standpoint. We cannot run studded tires on the metal rollers. Be sure all your tires are in good condition and are inflated to the factory-recommended psi. Tires that are underinflated or damaged can cause serious damage to your car, our dyno, and to anyone standing near or around the car. A tire failure on the dyno could potentially be lethal so please be sure your tires are in good condition. We absolutely will not dyno a car with studded tires, tires with metal cords showing, tires with screws/nails/staples in them, or tires with any visible damage.

Should I check my vehicle fluids?

Check all your fluids before putting your car on the dyno. Should be a no-brainer but roughly 10% of the cars that go on the dyno are low on oil, to begin with.
