As above

who would you recommend to turbocharge an e34 525i?

In the US there's plenty of them but in Europe it's all more ush ush and I feel like actually turbocharging that engine is frowned upon

My tuner (from Germany) says his main concern is the ECU which can't handle forced induction so I went online and was told that Haltech makes the best ECUs for multi parameter adjustment in BMWs (so, great for going turbo)

Anybody here has done it?

Thoughts? Opinions? Pointers? Tips?

Thanks in advance
