Please answer all of these questions to the best of your knowledge so the process of tuning your car goes as smoothly as possible and you get the most for your money. This is designed to benefit you so this process is as smooth as possible and that you do not show up with a car that cannot be tuned or does not meet your goals.
We will be taking your car to speeds in excess of 100 mph on the dyno. If you are not comfortable taking your car up to 100 mph then it is not ready to be dyno tuned. If your car vibrates or pulls to one side at high speeds we can not tune it.

Do you have any other modifications? If so, please list
What kind of fuel is currently in your car? (91 non oxy, 91, 92, 93, E85, or other)
What fuel are we tuning on? (91 non oxy, 91, 92, 93, E85, Flex Fuel, or dual tunes)
Do you currently have or have had any Check Engine Lights? (We CANNOT tune a car if it has a check engine light due to any mechanical problems, if you currently don’t have any codes but get a code after the car is running on the new base map we provided, please update us with what codes you have. Your car should NOT have any check engine lights when you come in for the tune.Examples: Front O2 Sensor - P0031, P0032, P0053, P0131, P0132, P0133, P0134 System too lean/rich - P0171, P0172, P2096, P2097 Speed Sensor code causing limp mode - P0500 MIVEC Codes - P0010, P0011, P0013, P0014, P0016, P0017 Again if you have any of the codes listed above we can NOT tune your car.

Again if you have any of the codes listed above we can NOT tune your car.
Do you have ANY mechanical problems? (Example- Running Rich, Will not idle, Poor fuel economy, boost/vacuum leaks, Not hitting target boost, Overheating, major oil Leaks, or any coolant leaks. We can not tune a car with mechanical problems.)
How many miles do you estimate are on your clutch, is it a stock or aftermarket clutch, and do you suspect it's slipping? Knowing how many miles on the clutch or if its slipping are important because we can not tune a car with a slipping clutch. If you suspect it's slipping it would be a good idea to get it replaced before the tune, If it slips on the dyno we unfortunately have to stop tuning and you will be charged for the time the car was on the dyno and will have to schedule another time to finish the tune after the clutch is replaced and broken in. Knowing what clutch you have is important because they are rated on the torque level they can hold. If you request a torque level higher then it holds and we go past that level and the clutch slips we will have to stop the tune there. The clutch may continue to slip even if we lower the power and you will ultimately have to replace the clutch.
When was the last time spark plugs were replaced and what were they gapped to? (If you do not know or have more than 15000 miles on them we highly recommend replacing them.) Recommend Gaps EVO 8 - .023" EVO 9 - .023" EVO X - .023"
Do you have any exhaust leaks? (Any exhaust leak can throw off either the factory o2 sensor or our dyno Wide Band Sensor and cause the fueling to not be tuned correctly.)
How Strong is your Battery/ Alternator? (We can not tune with a dead battery or a charging system that does not work)
What are your Power Goals/ Expectations and Intended use i.e. Drag Racing, Road Racing, Auto-X, Daily Driving, Racing in Mexico, with your tune? (Letting us know all your expectations of the tune prior to the tune will help us guide you in the right direction as you may not have all the necessary performance parts to achieve your goal.)
