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.
This is the support forum so you're generally only going to read about people asking for support here.

But it seems like you're confusing chassis though. The N63 and N63TU from F chassis are the problem children. Especially the older N63 which is deeply flawed from the factory to the point of serious recalls for misfires and other problems that always wind up becoming our headache to support when people tune them.

G chassis and the newer models never an issue.
