I don't know how reliable the source is, but someone posted on another site that Dinan has completed testing and is starting initial production of their full intake for the F10 550i. It was reported that it has been tested to give a 30hp gain, which makes sense given the restrictive intake on the N63. Don't know if gains are additive with other stages, but somewhere around 530 hp with stage 1 or 2 tune and intake sounds nice. Hopefully we will see this become available for the x5 50i in the next few months. Hopefully other tuners will follow with other intake options.
