ECU tuning FAQ
Will a tune hurt my engine?
A good tune stays inside safe limits for your hardware and fuel. We start with a health check and baseline logs, and we won't push a car that isn't ready for it.
What fuel do I need?
Most stage 1 tunes run on 93 octane pump fuel. Ethanol blends give more power and more knock margin. We'll set the tune for what you can actually buy.
Can I go back to stock?
On most platforms, yes. Your car's original software can be saved and flashed back. Ask us about your specific car.
Do you tune remotely?
Yes. If you can't come to Dallas, we can work through remote tuning with log reviews and revisions. Contact us with your car and setup.
Does tuning affect my warranty?
Modifying the engine software can affect warranty coverage on related parts. We'll talk through the trade-offs for your car before any work starts.
