I meant to say Racechip in title.


Now that both have been out for a while now..i am planning on buying one of the two for my 2016 550xi..for the N63tu engines which one of these chips works better..do any have codes associated with them that pop up or reliability issues..all suggestions welcome.


Thanks guys

Contact Ben ( forum member r33_RGSport ) for Racechip questions/purchase. Excellent customer service and a good guy to deal with.

Both work the same exact way and are stage 1 tunes that add boost.

I would get the JB because it is cheaper ... If you want more control get the JB4

Thanks guys will do
