Hi Guys!
I exchange pulley in my lexus from 130 to 150mm and fixed black box from Patrick L. I have a problem as the car does not go smooth (it is fine up to 4000rev but above that the bost is going down from 0.4 to 0.2). What do you think about that? Do you think there is a problem with injectors as there are still oem?

Regards
Bart

You need bigger injectors. Also check if the belt is tight enough. Maybe it slips in the higher revs. Also check all the silicone hoses if there is no leak

Do you think green injectors should be fine? I ordered from eBay.

I can only tell you that thise injectors will be good with 145 mm pulley. Not sur if they are big enough for the 150 mm
