Arrive On Time
Please try to arrive ON TIME. A good measure would be to arrive at least 10-15 min early. Trailered vehicles should consider arriving earlier. We have and will turn away customers for tardiness and/or time constraints so please be on time.
Wheel Lock Keys & Requirements
Please be sure to bring your wheel lock key(s) as it is required to remove the drive wheels for the Dynapack Dyno. Rear wheel drive vehicles must have adequate clearance for floor jack, diff access i.e no rear diffusers.
Electronic Devices include fuel controllers, piggyback systems, AFM or MAF delete devices, boost or timing controllers. Make sure your electronic devices are connected and working properly. Please also make your communication cables is accessible for the tuner (i.e. USB or Serial cables).
It is extremely important that you run high quality gas 91 octane or higher depending on your what your setup requires. BlackTrax offers tuning of race fuels and alternative fuels such as Methanol, E85 and E100 ethanol. Flex-Fuel tuning is also available.
How is the car running? Are there any significant issues we should be aware of? Please let us know before your appointment.
Look under the hood and check that all wiring connections are fine. Check coolant and vacuum lines for leaks. Make sure you don’t have any surprising check engine lights that may hinder your ECU or engine performance. Check all your fluid levels and top off if needed. It’s a good idea to do an oil change before dyno tuning. Nut and bolt check the engine, drivetrain and suspension.
Spark plugs are cheap. If you have over 30k miles on your plugs, it’s a good idea to change them before tuning. Please make sure they’re gapped before installation. We can provide new plugs before your dyno session, however the install will cut into your dyno time. Please call a day in advance to place your spark plug order so we can have them waiting for you on your dyno day.
Common Plug Gaps:
Colder Heat Range Plugs Commonly Used:
Intake and Intercooler Piping
Clean your air filter: Often overlooked, clogged or poor flowing filters are one of the most common root causes of low horsepower. We recommend high quality element air filters. Most knock off brands have resulted in loss of power due to flow restrictions. Forced induction setups should inspect all intake piping and intercooler piping connections. Make sure clamps are tight and welds are complete. Please also make sure your pipe connectors are not dry or cracked. We recommend 3-4 ply high temp silicone connectors because of their high heat resistance and flexibility properties. Vanjen clamps are a stronger form of connecting pipes commonly used in professional competition vehicles.
Inspect the exhaust system for leaks and dent. Leaks and dents can result in loss of power. On turbocharged setups, exhaust manifold leaks will not spool the turbo effectively, causing unstable boost levels. It is not recommended to change your exhaust configuration after custom tuning. Engines tuned with a full exhaust system may operate leaner when removed. If the exhaust configuration has changed after the tune, we highly recommend a revisit for a touch-up tune.
Please check for fuel, coolant or misc oil leaks. Due to the obvious potential risks, BlackTrax may refuse to dyno a vehicle if it has signs of fluid leaks. The technician and/or tuner reserves the right to make this decision.
A WORD FROM BT
Our goal is to provide you with a safe, exciting and rewarding experience with your tuned ride. PLEASE try your best to refrain from excessive communication with the tuner. Ultimately, this may impact your tuning time and may potentially promote errors. Your tuner will provide you with an overview of your session after the completion of the tune, and provide you with comments, tips and advice.
