Please somebody help with the Level D sounds!

It's just really annoying me now. I love a good sound pack for my aircraft the level D's default engine sounds wasn't too good. I've replaced the sounds with TSS some nice sounds of AVSIM ETC! IT STILL DOSEN'T FIX THE PROBLEM. So the problem? Well it's the engine spool up sounds. The sound isn't synchronizing with the fan blades or N1%. Instead the sounds are synchronizing with the throttle positions, so therefore the sounds are terrible the slightest twitch of the throttles and it sounds like revving a car up. Other people have expereinced this before can anyone help me with this issue?

Thanks,

Tom
