"problem" is in the eye of the beholder. the response rate of the analog T700 is eye-watering, especially compared to older helicopters. The fuel control easily responds to full power from zero power in 2 seconds without drooping below about 95%. If it is a "problem" there might be some reason why a tactical utility helicopter is placed into situations where it needs to withstand 1 second full power pulls. These engine acceleration rates are dictated by the engine design, not the fuel control, since the stall protection of the engine dictates the max power rate.
