Heya,
Took the car out for a spin today and put her onto high boost for the first time in a while.
Noticed that the car isnt holding boost, its going up to .9 bar as it should, but then as I go up the revs its dropping to .6/.7 bar. Feels slow :confused:
Anybody got any ideas what it could be?
She single or twins mate??

Check all the small vac lines that go to the actuators for the second turbo.... pre spool & the one by the Y pipe...... if these aren\'t working properly then your boost will drop off as he RPM increases, because the primary turbo runs out of steam at avout 5k which is whan the 2 turbos should be in full flow!
aah thats sounds like it could be the problem then.
i`ll have a dig about and see what I can find, am I looking for pipes that have completely come off, or pipes that have cracked or split?
eather or mate.... as a split pipe will be enough to stop the system from working!! also could be a blown solonoid under the UIM.....
Mass of possibilities, just a process of elimination!!
