Question Strange sound from engine bay (fmu?)

after finally getting my begi s kit fitted, i took the car out for a light drive today with no boost as am getting the timing done on friday.
When applying the trottle and the revs begin to rise when moving, a strange wine comes the the engine bay, its sounds like it may be coming from the begi FMU. can anyone advise me on what this could be and also is it normal, or can i stop it?
Thanks

If you are getting a whisting noise, that might be the FMU. In that case, you had some dirty fuel run thru it and need to replace the shims. Shoot me an e-mail or call, I can send you some.
