Hey guys, as i know bmw 320d 136 hp has turbo GT1549V.
Can somebody tell me what's the safe upper limit ?
I attached my boost map, do you think that is safe for this turbo ?

I saw information about it, and it listed is like 2.5 bar maximum...
I think this turbo can keep up to 2.5 bar. But it's maximum is for short time....
If you look at stock boost limits, it's usually 2.25...

I hope i`ll be fine with 1.35, i`m running with this pressure for more than 1 year, without problems :)

You can feel the differences, especially in hot days, from 1.25 o 1.35 boost. You mean 2.25 absolute pressure right? not boost.

on vw golf tdi it is safe to run it on 1.35, same model so it is fine

Good to know.
I`m little bit afraid because a friend from forum with same car and 2350 mbar boost just fucked the turbo.
Found some metal parts in intercooler and missing 1 liter of oil from engine :) I think gone in turbo and after that to exhaust/intake
