Flow-Matching Options

 

Every CS Performance injector set is individually tested and dynamically flow matched before shipping. You can choose between our included standard matching or upgrade to our most precise matching service.

 

Standard 3–5% Dynamic Flow Match | Included
Every set is dynamically tested and matched so the injectors flow within approximately 3–5% of one another.

This option includes:

  • Individual testing of every injector
  • Dynamic flow matching to approximately 3–5%
  • A professionally matched, installation-ready set
  • No additional charge

This is a solid choice for most standard replacement applications.

 

Precision 1% Dynamic Flow Match + Results Sheet | Recommended Upgrade
If you want the closest injector-to-injector consistency we offer, choose our Precision 1% option.

Our technicians test and select injectors to build a set that is matched within 1% of one another under dynamic flow-testing conditions. This requires additional testing time and a larger selection of injectors to create an exceptionally closely matched set.

Your upgrade includes:

  • Precision matching within 1%
  • Additional individual testing and injector selection
  • Our most closely matched set available
  • A printed flow-results sheet showing the measured results for your specific injectors

 

If you are already investing in a complete injector set and want the most consistent set possible, we recommend upgrading to the Precision 1% Dynamic Flow Match.

 

Important: The Advanced 1% Flow-Matching fee is a service charge and is non-refundable once the flow-matching service has been performed.
