🔧 What it is
Software-only upgrade: No physical hardware changes required.
Optimized for stock parts: Uses factory intake, exhaust, and turbo.
Dyno or generic map: Can be custom-tuned on a dyno for your car, or a generic "off-the-shelf" map from a tuning company.
Turbocharged petrol/diesel: +20–40% horsepower, +20–40% torque.
Naturally aspirated petrol: Small increase, ~5–10% power.
Throttle & drivability: Sharper throttle response, smoother power delivery.
Fuel efficiency: Sometimes improves at cruising speeds (if you drive gently), but usually worse if you use the extra power.
Noticeable performance boost for minimal cost.
No major reliability issues if car is healthy and serviced.
Reversible – you can flash back to stock if needed.
Increased stress on engine, turbo, clutch/gearbox.
May void manufacturer warranty.
Needs high-quality fuel (some maps require higher octane).
If your engine has underlying issues, a tune can make them worse.
