For engine repair and rebuilds, see our Engine Repair page. This page is about tune-ups and performance, not major engine work.

Common signs to watch for

A rough idle or misfire, hesitation or lack of power, a check-engine light with misfire codes, or poor fuel economy are all reasons to consider a tune-up. These are general symptoms, not a diagnosis — we inspect before we recommend any repair.

What's included in a tune-up

It depends on your vehicle — spark plugs, ignition coils, and throttle-body cleaning may all apply. We confirm what your car needs after an inspection and explain the work before we start. We don't clean throttle bodies on every vehicle — it's part of a tune-up when your vehicle needs it.

Performance enhancements

We offer performance enhancements intended to support engine efficiency and driving performance. We don't list specific upgrades like ECU tuning, turbocharging, superchargers, engine swaps, exhaust upgrades, or dyno tuning here, and we don't promise horsepower or fuel-economy gains. Call us at (407) 656-8800 to confirm the exact performance work we offer for your vehicle.
