I just got my car back from servicing at the dealer and now it runs terrible.
The dealer I went to is not a Dinan dealer. They asked if I had the software download when I picked it up. I said yes.
On my way home, it was revving very slowly and sounded flat. This occurred for 10 minutes then it cleared up. So I didn't worry about it. Today, it started acting up again. The car feels like it lost 50% power, redline is back to 6900 rpms and is running hot.
I just had the oil changed and had them run a diagnostic check of the systems. I will call my dealer in the morning to see what they did.
Steve is right! if those knuckle heads harnessed into your computer port, they could have possibly overwritten your Dinan software??
My suggestion: Don't bring your car to another dealer for service. Unless of course, the place that installed the Dinan software is unable to service your car? Are they not a BMW Dinan authorized dealer?

Very confused. What difference does it make if he has the Dinan software upgrade, he won't lose 50% of his power and the car won't sound flat. I agree that the Dinan software maybe erased and need to be re-downloaded, but he shouldn't lose soo much power. Is the Dinan dealer required to put a sticker on the CPU unit or harness?

My technician read the error codes on my car this morning and it appears I have a bad camshaft sensor. The sensor faulted several times according to the BMW computer. By the way, that DIS machine is pretty cool.
I believe when the sensor went bad it ******ed the timing heavily, which explains why my car felt like a 318i. Apparently the engine's computer overides the Dinan revised redline and reduces it to 6900-7000 rpms when it senses problems. This morning when the sensor did not act up, the redline was back to 7300.
Hopefully it will be replaced tomorrow. I guess it was just a coincidence that it went bad the same day I took it to the shop for servicing. Thanks for your help. Hopefully I will have all 394 horses tomorrow.
