Terry..... gotta be honest. I just read through every post on this forum..... and every single one of them are people having problems using a JB4 on this platform.... and even unstances of you saying that tuning this platform is complicated.

That concerns me.... a lot.

I never had any problems with my JB4s on my last 2 BMWs..... this has me deeply concerned though.

There's no "success" stories anywhere.

Particularly for only "maybe" 30-40 hp.

2020 X5 M50i - on order. ETA Jan 2020.
