- Holley & FAST
- Factory OEM
- Race calibration
Calibration work
Fuel and timing maps that actually match the build.
Whether the issue is a fresh swap, a hot-start problem, or a combination that feels flat up top, Foulks Performance tunes for the way the vehicle is really used. The goal is cleaner drivability, cleaner pulls, and fewer mystery problems after the build is done.
What's included
EFI work from base-map setup to top-end tune.
Base-map setup
Initial EFI configuration for swap builds or new installs so the engine starts, idles, and drives before fine-tuning.
Street tuning
Drivability calibration for idle, cruise, part-throttle, and wide-open-throttle so the car actually works on the road.
Performance tune
Fuel and timing calibration that matches the combination and delivers the power the build was planned for.
Forced induction
Tuning for turbo and supercharged combinations where fuel and timing have to be handled carefully to protect the engine.
Drivability fixes
Stumble, surge, hot-start issues, and poor fuel economy diagnosed and corrected through calibration instead of parts swaps.
Holley & FAST support
Standalone EFI experience with Holley, FAST, and other aftermarket systems including sensor setup and wiring integration.
Who it's for
Builders, racers, and daily drivers who need the tune to match.
EFI tuning is where most builds either come alive or fall apart. A combination can have all the right parts and still run badly because the fuel and timing do not match. Foulks Performance handles EFI tuning as part of build work and as a standalone service for customers who have the engine together but need it dialed in.
- Swap builds that need initial tune setup
- Performance engines needing top-end calibration
- Daily drivers with drivability or economy problems
- Boosted applications that need careful fuel and timing work
FAQ
EFI tuning questions, answered.
What EFI systems does Foulks Performance tune?
Holley EFI, FAST EFI, and factory OEM systems including GM, Ford, and Mopar. The shop handles base-map setup, street tuning, and performance calibration.
How much does EFI tuning cost in Stillwater, OK?
EFI tuning cost depends on scope — base setup, street tune, or full performance calibration. Tony provides pricing upfront after understanding the combination and goals. Call or text (405) 714-8364 for a quote.
Why does my car need EFI tuning after a build?
After engine work, cam swaps, forced induction, or heads/intake changes, the existing tune no longer matches the engine's new airflow. Proper EFI tuning matches fuel and timing to the new combination.
EFI tuning vs carburetor — which is better?
EFI offers better drivability, fuel economy, cold-start behavior, and adaptability. Carburetors are simpler and cheaper upfront. For street-driven builds, EFI is usually the better long-term choice.
Can EFI tuning fix drivability problems?
Yes. Stumble off idle, hot-start issues, surging, and poor fuel economy are often EFI calibration issues that can be corrected through tuning instead of parts swaps.
