I have a feeling my car is leaking turbo boost, it doesn't throw me back in my seat anymore. where can I go to get it diagnose and fix in Chicago west suburbs?

[Cloud9blue]

stock? or tuned?

Send it to either A&L or LukeG if you need a shop to take care of it.

jb4 and dci, that's all I have on the car right now.

why not just log from jb4 and figure that yourself.

^ +1. Do some logging to see what's going on.

I did download the hex file but when I clicked on the jb4 application it doesn't open. I don't really don't want to mess anything up. After 12grand getting everything right at Westmont bmw, I only paid about 30% of the 12k but still I'm not very confident messing around with the car. I actually did brought it to the dealership 2 weeks and my SA told me nothing seems to be leaking.

Read read read. LOTS of great info on these forums to help you with not only this issue but the many more you're bound to experience going forward.

Figure out how to log and read codes thru your JB4. That will help a lot.

Also what map are you running? And since you have JB4, set your boost to your fuel gauge with JB4 (setting 2/1) and tell us how the boost is coming on (ie: if you're getting any boost, if its slowwwwwly boosting, etc.)

You can buy an 07-08 335i for $12k. Not sure what work you have them done there, but it sounded like the dealer made some good money off of you even if you only paid 30% of that.

[long335i]

You're right! The only good thing is my SA gave me loaners everytime I bring it in. This car is nothing but problems for me since I've owned it. Don't get me wrong I love driving the car, I just don't love having all these problems. The dealership I got it from is getting sued by other buyers as I'm typing.

[long335i]

But enough with that, makes me mad just talking about it. Anyway
I will read and research on the boost leak subject, thanks to all that replied.

I'm running map 5 right now, my boost is around 13 as I can see it from my oil gauge, but it just doesn't pull like it was before. I switch to map 1 and getting 10 psi, from what I've read, that seems to be normal.

Read up n54tech.com. Run a backend or MHD flash. All the information is there on that forum for you to read.

And log. We can't help you if you don't even have a log of what's going on.

we don't see anything...

screenshots of your logs are useless, you need to post the CSV file or upload them to datazap.me

Make sure you log at wide open throttle (WOT). Do a WOT log in 3rd and upload that. I found that the onramps for 290/355 work great for these logs.

[long335i]

i think this is the 2nd part of it, i did 2 log.
