where can I purchase a 0.9 bar spring for the stock wastgate ?
Thanks

do I need 38 or 44 MM for the stock wastgate?

I believe that Tial wastegate springs will not work in a factory wastegate.
Spring sizes available for the factory wastegate are .7 bar , .8 bar, 1 bar and 1.2 bar.
The .7 and .8 wastegate springs are, to my knowledge, only available as used. The 1 and 1.2 bar springs are available from Weltmeister through Performance Products.
To achieve .9 bar you will have to do one of the following:
(1) Buy a Tial 46 mm wastegate as James has stated and select the correct spring that yields .9 bar on a boost gauge (on my 965 with a stock exhaust that was a .8 bar spring).
(2) Find a factory .7 or .8 bar spring, install it, a mechanical boost controller and a mechanical boost gauge and adjust until you achieve .9 bar.
