ECU tuning for Z4 sdrive23i

hey guys, i was on the BMS powerbox previously for 10 months, but decided to take it off after much hesitation. and also due to my modifications to my exhaust and intake.

Anyway, I am thinking of using UNICHIP for my N52B25 engine.. anyone have any comments or any advice regarding this mod? thanks in advance!

No Unichip experience with BMW however I do have some with Subaru and Toyota. Personally I am not impressed with the results I have experienced. They are local to me so I have been in the shop. In my opinion they are way too expensive for the small gain.

I used Unichip in my E60 M54 engine with a significant gain (+30 BHP from dyno) It last for 2 years and need to remove (engine can't start)
The ideal tuning should be OBD2 flash which is completely reversible. I found a device call "BlueFin" but the have only for turbodiesel engine
Anyone knows about OBD2 flash tuning for non turbo engine please help
