On another note i had the tests done today. Leakdown test all cylinders 100% no leakage.
Compression test
Cyl 1. 160psi
Cyl 2. 150 psi
Cyl 3. 155 psi
Cyl 4. 150 psi
Cyl 5. 150 psi
Cyl 6. 150 psi
Ocha im not sure what stock psi is supposed to be and neither did my technician. Any info would be appreciated. Oh and does anybody know what bmw uses for stock spark plugs. I assumed bosch but the plugs i have are ngc.

compression numbers are solid, but there is no such thing as 100% no leakdown, so either the person that did it lied to you or doesn't know what they are doing (leakdowns actually pretty complicated)

While that is BMW spec, you can't use an absolute value comparison for compression tests, only thing you can do is compare between cylinders for variance.
