Boostpressure too high NG93 1,8t bsr

[AkiTom]

Hello

Boost pressure ( stage 1) peaks 3-5th gear around 1,6 bar and i think that it`s too much. If i return standard software, pressure is what it should be ( around 0,5 bar).

Any ideas why? Ok it`s very warm weather here in Finland ( 26-28c), but still...

Hi Aki

What stage (from BSR) do you have? Start by check all rubber tubes/hoses - they should be soft, if not, replace them. Pay extra attention to the hoses near turbo.
1.6 bar sounds a little to much. Does it run smoothly?

Hello

Car runs smootly, except clutch starts to slip. We propably found the reason, why boost pressure is so high. We did some logging with Tech and came up, that atmosphere pressure reading ( ecu) is 39kpa. As far as i know, it should be 100kpa ( 1 bar).

Well only problem is now, where the signal comes??? My 03-04 sensor near fuel pressure regulator, but my06 there is only empty space.. Wis Don`t know??

Anyone???

One guess is that it comes from Evap pressure sensor. But it`s only guess until some facts cames from Saab. Hopefully
