Hello all again.  

This image,  if you can see it,  is off an odb2 reading,  bottom left,  of the vacuum reading.  Is it correct?  Normal driving was about - 25 and when boost kicks in its up to +10. It means absolutely nothing to me,  but there is a problem somewhere as it's really hesitant and judders when giving it some.  No codes present,  and I just changed the maf and the y shape breather pipe on the top for a new blue one from creation motorsport.  Any other ideas,  I'm putting it on my ramps Thursday morning to check it out below and the other pipes to see if they ain't split too.

Yes that's right, under - 15 and one of the vac hoses is split

S pipe maybe.

I replaced my y pipe and it was still juddering till I did the s pipe.

Ment that a reading of -25 is healthy

Would you say that a split vac pipe is not the problem then raf? 

When my S pipe was split torque readings were a maximum of -9, soon as the pipe was replaced it went to -20's. I'm no expert, I could be wrong but you have good vac figures.

That's a shame lol,  I was hoping for an easy fix.
