Dinan boost controller - thoughts?

[JimA]

I'm enjoying my new (to me) 2017 44i with a B58 engine and I'm thinking I would like to get some more power out of it, but not at the risk of greatly increasing wear or damaging it. I'm looking at two boost controllers by Dinan. They make the "sport" and the "elite." They both seem to give an additional 10% HP but at very different price points.

Any of you guys have any experience with these? What do you think?

Did you buy either of the boost controllers. If you did which one and how did it work out?
