Jb4 for xdrive50i, who's done it?
Searched all the forums and can't find much info on this. Wife wants louder exhaust and more power from the 4.4 turbo (can't say no to that). Coming from the cayenne turbo, I agree though this truck is nearly as fast. Who's got the jb4 and...is it worth it? I'm thinking dp's also but the jb is first on the list. 40whp seems like a low gain for a v8tt..but, it is almost 10%. Thanks guys

OP- if you are eventually going catless why don't you look at doing a flash tune through Velos or AA? Omar at Velos provided me with a tune when I went catless and I am very happy with it. Just a suggestion. |

The link does have JB4 in it, but that means nothing. I used the JB4 interface to configure my Stage 1 tune, but that doesn't make it a JB4. Just wanted to make sure that the OP understands this before he wastes money or does something far worse with an incompatible tune... |

LOL - I believe you are correct stage 1 is NOT a jb4. More of a jb+ , simple boost controller. The stage 2 upgrade is the jb4 or maybe the simpler jb3 in jb4 housing. It's pretty rough to install because it's not plug n play. Comes as a pin out installation, so not to many people are gonna be willing to do that. That stage 2 forum has most of that info, and most of the guys are running stg 2 on 550s.

Does the Stage 2 work yet on the X5 50i? It's listed on their compatibility page. Though, for whatever reason they are missing the year 2013.

I know this is a JB4 thread, but doesn't ESS offer a straight up tune (no other parts required) for the N63/50i? I put one on my 2012 50i and dropped 1+ sec off my 0-60 times. Price was ~$1k at the time a couple years ago.
Thought that would scratch my X5M itch. It did for a while at least. haha |
