Please only fill out this form if you have a tune scheduled or have purchased a base map!
Due to the Covid-19 pandemic we will be allowing only the owner of the vehicle to wait while the vehicle is getting serviced and allow you to watch the tune from outside. But we are not allowing big groups of customers at our shop and are only trying to provide essential services to keep customers' cars running healthy. This is to protect our employees, our other customers, and keep us open. So if you bring any friends they will have to wait outside the entire time.
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.

If you have a built heads, please list any known part specs/brands
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 have an aftermarket AFR sensor wired into the ECU? If so, what ECU pin is it wired to? (We can not tune your car with only the factory O2 sensor. In order to have full closed loop control of the fueling we require an aftermarket AFR sensor such as AEM or Innovative. If you don’t have an AFR sensor or are unsure or need one wired in please let us know and we can schedule a time before your tune to wire it in.)
Have you connected to your ECU with a laptop and confirmed all sensors are reading correctly? (We need all the sensors working and reading correctly. Example- Intake and Coolant temp reading what you would expect? Is the Throttle Position Sensor (TPS) calibrated and reading 0-100%?)
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 - Examples: front O2 sensor, TGV stuck closed but not deleted, speed sensor code causing limp mode)Please list any codes
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.)
When was the last time you changed oil? (If it has been more than 2 months or 2000 miles we highly recommend changing your oil before the tune.)
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 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.)
Do you have any parts needed prior to your tune or any parts installed? (Our expert techs install performance parts all day. Our labor rates are very fair. And our expert support can help you decide which parts to purchase from us to achieve your goals.)
Do you need a base map to drive your car to our shop with the new parts installed? (If you have a Cobb Accessport, we can email you a base map to drive on with your new modifications. It can be unsafe to drive after installing modifications. Having a base map allows you to drive your car and double check it rather than waiting and towing it in and not being able to double check everything.)
If you have anything wrong with your car that needs addressing before the scheduled tune date, you will want to let us know. Our expert technicians can be booked out as well, so you will want to get on the schedule to be ready for your tune.
If you have parts that you want installed prior to the tune or need parts you will want to let us know. We can help you get those parts since we are distributors of most performance brands 220.127.116.11/parts
