RON 99

Car feels great!

Engine light comes on steady or flashing at high rpm in Map 4. Car then judders and vibrates and struggles to accelerate. Issue resets if you turn ignition off/on again. Fault codes relate to multiple misfires

Car feels good. some pulls feel stronger than others (could just be me)

Limp mode - underboost fault in Map 3. Fault persists after reset
