Why does Mazda rx7 13b turbo dump all boost at mid throttle acceleration?

The Mazda RX-7's 13B turbo engine may dump boost at mid-throttle acceleration due to several factors, including a malfunctioning wastegate, boost control issues, or vacuum leaks. If the wastegate is opening prematurely or not functioning correctly, it can lead to a loss of boost pressure. Additionally, problems with the turbocharger itself or the engine management system could disrupt optimal boost levels. Diagnosing the issue typically involves checking for mechanical faults and ensuring proper tuning.
