Injector flow matching
At high boost and horsepower, small differences between injectors turn into lean cylinders. We test every injector and match the set by measured flow.

Who needs flow matching
- Supercharged and turbocharged builds
- E85 or flex-fuel setups running near injector limits
- Engines with a history of one lean cylinder
- Anyone tuning on a dyno who wants consistent cylinders
What we do
- Clean and service every injector
- Flow test each one and record the numbers
- Group and match the set by flow
- Send a report with every injector's numbers

Common questions
Do I need to send extra injectors?
If you want the tightest possible match, sending a few extra lets us pick the closest group. Ask when you start your order.
Does this include cleaning?
Yes. Every injector is cleaned and serviced before it's flow-matched.
