Hooked it up to Multiecu yesterday and got the ollowing results (see pic)
These were done in 3rd gear from 2000 to 3000 rpm.
Car is remapped.

It seems awfully high :paranoid:

add vnt % and repeat at your own risk, that's dangerously high boost for the turbo if accurate.
got swirl flaps ? may be broke in shut position .
vnt seized in max spool position
inlet manifold coked up to point of restriction
map sensor caput(does it read near atmospheric at key on or idle)
mapping issue
also add total fuel mm3 to log also
history behind this issue ? just mapped or just started overboosting

I've had issues since I bought it a few weeks ago. Code P0237 and limp mode. replaced MAP sensor with a genuine Bosch. EGR is blanked at the bottom (at the egr pipe) Not mapped out, but no EGR error codes. At times is won't move as fast as normal when accelerating even though the boost gauge shows nearly max. this usually goes away when I let off the pedal for a bit then press it again and it pulls very strong again.
It's a 2008 159 1.9 JTDm 16v. I've actually done the Mr muscle 'clean' today and the actuator does move. I can get it moving easily by sucking on the vacuum pipe. Just not sure if it moves the whole 10mm.
Not sure about swirl flaps. I have the plastic inlet.
I have spoken to the guy who mapped it in September last year and no issues were reported then.
