FREQUENTLY ASKED QUESTIONS

Common Questions

Ask what the tune changes, what fuel it requires and how the shop checks the result. Discuss your vehicle’s current condition and any modifications already fitted. A reputable tuner should explain trade-offs plainly and avoid promising power gains without a supporting test.
It can. Misfires, boost leaks, worn ignition parts or fuel-delivery problems should be diagnosed before changing engine settings. Tell the shop about hesitation, warning lights, smoke or unusual noises, and ask whether it will scan the vehicle and check for faults first.
