Took my mate out in the scoob yesterday and he seems to think I might have boost leak because:
1) You get a high pitched whiring noise when the turbo spools up 2) The boost guage peaks and drops under full acceleration
I thought the noise was just a characteristic of the turbo (just got a VF43 fitted) but i must admit my old td04 never made this sort if noise
Also is it normal for the boost gauge to peak then drop or is it meant to peak and hold?
I think it's probs ok but jus wanna double check on here!
Cheers
Dean.

If you have just had it mapped it must be possible leak as the mapper would had noticed anything wrong at the time of mapping

it isnt normal too hear a whining noise on boost, as already said it sounds like a boost leak..
but the boost dropping off is normal on a vf.
will be mapped too maybe 1.4-1.5 bar peak
but boost tail off at the topend ov the rev range

Mines more of a whistling noise more than a wine noise
