s60 2.4 t5 2006 B5244T5 wastegate setting

Hello, i adjusted my wastegate according to the vida specifications. 0.7 bar, 7mm travel with digital gauges and accurate.
With this settings the car is overboosting.
I reduced the preload step by step, now with three turns lower then the vida spec its working without overboosting. The base pressure without TCV is now 6.5 psi, 0.45 bar.
With TCV connected the car boosts to 14-15 psi 0.95- 1.0 bar. I think this is for a stock software to much, but it works good without stutters or anything.

Can anyone provide me the correct base pressure with TCV disconnected, that i can adjust it perfect.

I think it stands in the ecu software but there is no way for me to look at it.

PS the car has the m66 manual Transmission.

Many Thanks

My car boosts 1 bar at full boost since I purchased it 10+ years ago. I have never adjusted the wastegate, so it is set correctly from factory. I have never tried adjusting and have not measured pressure without the TCV.

Any reason you think that 1 bar is too much for the OE tune?
