MAGNUM DIESEL TURBO UNDERBOOST

2008 Chevrolet Optra • 15 miles

I own optra magnum diesel 2008 model, mileage run 75000km. Since 50000km my car pick up got down. If the car crossed 130km/hr and made it to run for 15 min, then turbo charger gets under boost and some check light is glowing, if I continue driving after glowing check light car not crossing 100km/hr, by observing with tech2 service persons are clearing the problem and the same was repeating if the car crossed 130km/hr for 15 mins. Service persons cant find the solution till now
