Why does your engine stall with turbo anti-lag system?

An engine may stall with a turbo anti-lag system due to inconsistent air-fuel mixtures or inadequate fuel delivery when transitioning between throttle positions. The anti-lag system maintains boost pressure at low RPMs by allowing unburned fuel to ignite in the turbo, which can sometimes lead to a rich mixture that disrupts engine operation. Additionally, if the system doesn't effectively manage the timing and boost levels, it can cause a loss of engine control, leading to stalling. Proper tuning and calibration are essential to prevent these issues.
