Default 2005 525i m54 a/c not cooling enough

I have problem with Ac, at vents on Idle I have Minimum 70F. Outside temp around 89F. No errors in Inpa. Pressure sensor ok. Blowers ok.
Low line at Idle 45-50 Hi line 200-225.
When I put more rpm pressure on Hi line go down to even 150 and on Low line go up to 65-70.
I don't know where can be problem. Compressor?
One more. Ikha don't have Vin number only ????? In ncs expert I don't have option to choose my engine. There is only m54 but 3.0l. I have 2.5l.
