Estimated Occupancy Weight (List the total weight that will be in the car for the logs, i.e. total weight of all passengers and any misc items in car. Listing occupancy weight will help give the Virtual Dyno graphs as much accuracy as possible.
Stock Downpipe or Brand (A GESi cat is needed to not throw the P0420 code. If you are catless or have any other cat than the GESi you will likely throw a P0420. We can no longer disable that code on an Accessport)
Stock Up-Pipe or Brand/ External Wastegate
If you have an EWG, please list the spring pressure
If you have an EWG, would you like there to be flutter or no flutter (ie. when the wastegate opens, do you want the exhaust to have a smooth sound or do you want it to have a fluctuation in sound.)
Stock Header or Brand

Stock Fuel Pressure Regulator or Brand (On 2008-2021 STI running aftermarket injectors we require a Cobb or other aftermarket fuel pressure regulator. The stock regulator is known to cause the 2800 rpm stumble that can't be tuned out.)
If adjustable aftermarket FPR, what is the PSI base pressure Recommended fuel pressure is 43.5psi. When setting or checking fuel pressure always make sure the engine is warm and you have the vacuum hose disconnected form the fuel pressure regulator.
Stock in tank Fuel Pump or Brand (Size)

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 performing logs for the E-Tune.
Examples:
Front O2 Sensor - P0030, P0031, P0032, P0131, P0132, P0134
System too lean/rich - P0171, P0172, P2096, P2097

Air pump - P2431, P2432, P2433
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.)
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 2002-2014 WRX - .028" 2015-2021 WRX - .021" 2004-2021 STI- .028" 2004-2013 FXT - .028" 2014-2018 FXT - .021" 2005-2012 LGT - .028" 2005-2009 OBXT - .028"
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.)
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.)
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 brandshttps://www.jmautomn.com/parts/
