Dinan stage 1 tuner question

[VeryFastF06VeryNice]

I picked up my 640 with a pre installed dinan tuner and the dealship wasn’t able to tell me much about it except that it was stage 1 and was installed when the car was brand new back in 2017. I honestly can’t find much info online as all the plug in ones don’t seem to fit my car even though it’s pretty much exactly the same thing as in the pictures online (pic of it provided below). If anyone has any general information on what power gains I’m getting (I’m assuming somewhere around 400hp on 93) and some other info on it as well that would be great! They took off the sticker next to it so I can’t get anything accurate online but I can provide any needed information. I’m also wondering if I can somehow configure it (dinan app just allows me to turn it on) and also if I can somehow change my hp reading on the sport displays as they’re still at 320. Thanks in advance everyone!

Give Dinan a call with the sticker information. I think they have a record with theVIN numbers.

I think that’s probably my best option. Called bmw a few weeks ago they couldn’t tell me much

Are those numbers accurate? I thought such numbers were only achievable for a flash.

I had a dinan plug in tune on a F10 (was smaller that your picture) but I had numerous issues with it. Got rid of it and went BM3.
