Ищем:
(L.L.engine_tank_content) 250 / (S.L.tank_percent)

Вставляем ниже:

' Turbolader:
(L.L.engine_n) (F.L.engine_turbo_RPM_factor) (L.L.engine_throttle_injection) (F.L.engine_turbo_throttle_factor) * 100 * (S.L.engine_turbo_RPM_soll) s0
(L.L.engine_turbo_RPM) s1
'Скорость набора наддува
2.8 s2
'Скорость сброса наддува
0.7 s3
(M.L.engine_traegheit)
l1 (S.L.engine_turbo_RPM)

Там же в engine.osc ищем:
(L.L.engine_throttle_injection) s1 (L.L.engine_n) s0 (F.L.engine_M_maxThrottle) * 1 l1 - l0 (F.L.engine_M_minThrottle) * + (S.L.engine_M)

Заменяем на:
(L.L.engine_throttle_injection) s1 (L.L.engine_n) s0 (F.L.engine_M_maxThrottle) * 1 l1 - l0 (F.L.engine_M_minThrottle) * + (L.L.engine_turbo_RPM) (F.L.engine_turbo_boost) * + (S.L.engine_M)

В самый конец файла вставляем:
{macro:engine_traegheit}
