hi all i recently got my hands on a 850R from a friend,
it had a few gremlins i managed to sort out in due course.
i noticed the plugs were very white so i replaced them anyway to me it suggested leaning out,
my mate had deleted the rear muffler and did a straight through from the cat.
just yesterday i was driving her a bit hard when i noticed that it strted to sound like a lawn mover
sort of lacking power somewhat yet no codes...
its not getting much more than 5-7 psi checked my vac lines they are good not damaged or leaking
im at a bit of a loss any one with some new ideas would be awesome

Have you replaced the PCV system? That is the heart of your vac system.

You can also pull the intake from your turbo and look into it with a mirror. See if there are any damaged fins (you may be able to fell them as well). Then you can try to push and pull the turbine in and out to see if it has any play which is NOT good.

the lawnmower sound and lost of PSI makes me think its the hose from the IACV. Mine did the same and it had a small rip in it that I couldn't see until I removed it.
