750 JB4
I recently bought a 750 CPOE.
Has anyone had any experience with JB4 or the Dinan stage 1 tune. I am probably doing one of them in the near future. The JB4 increase in power is more and is less expensive however Dinan comes with a Warranty. Any ideas? |

I went dinan, couldn't risk warranty issues and reliability. I had jb4 in past vehicles but felt a 750 called for something different for some reason. I think it may also have future updates for more power. I installled it last week, also programmed exhaust flap to stay open all the time. I love it. Looking forward to trying a launch sometime this week and have a service scheduled for a couple weeks out, Happy I don't have to remove it .

They said Dinan was just a stage 1 and it's "future proof" hoping that a stage 2 would not be that much more $$$ How did u program the flaps to remain open I have the M sport exhaust. Is it something Dinan installer can do?? Please share your Butt Dyno results compare to before the tune how much of a difference did u notice. Thanks |

Exhaust flaps cost 60$
30$ piece on amazon and 30$ app called BimmerLink and about 3 minutes of your time. Best mod I've done yet. As for butt dyno I've driven the car 100 miles since and in a lot of traffic and I did the exhaust the same day. I also only had the car for a week before doing it so I can't be a good judge. All I know is the car is a BEAST. |

There are better ones that are more expensive and faster but I like this price and I had a few extra seconds.... |
