Welcome! I'd love to see what a FBO 135i feels like. What's your mod list?
I love my 135i...

Thank you all!
The Acura was fun to drive but I also had to sink about 23k into it to get it there, and even with that it's just no BMW. It was a fun project but you just cannot beat the road feel of a BMW.
wasntm3, whereabouts are you? I'm moving in to a house right across the street from Hartbrook park.
suspenceful I'm always down for rides if you're local. I'm always looking for good people to have for photoshoots, as well. I still need some rolling photos of the car this year.
My FBO setup is Cobb tune, Cobb FMIC, Cobb drop-in filter, Maddad catback, and Akrapovic downpipes. I actually got referred to Pure Tuning over in Toledo, OH as their shop track car was a 135 that was being retired at the end of last season. They called me back once it was ready to be parted out and sold me the Akrapovic DPs for 900 bucks with only 2k track miles on them, which was a great price. We discussed intakes and he said they basically tried everything side-by-side on the dyno while they were setting the car up for the track and far and away the largest gains you're gonna see are from a good drop-in filter. Spending the extra cash on a pure aftermarket intake, what you're mostly gaining is in the filter.

Welcome aboard. Why does the car reek of oil - you burning oil?
Still researching - it was fine until I installed the downpipes, FMIC and more aggressive tune. You only smell it at stoplights when you're sitting still. Never when you're driving, getting after it, etc. I had read from others that they experienced similar thing after installing FBO mods due to the weak OEM PCV valve being prone to boost leaks, and that the Rob Beck PCV valve would be better.
I already replaced the PCV valve with the RobBeck, and added the BMS oil catch can too - that has not resolved the issue so I have to see where that leads. I haven't noticed any significant oil loss yet.
Problem is I'm in limbo right now - the place I'm living at for the next 30 days has no garage so I won't be able to inspect thoroughly until June probably when I move ;(

I'm up in the Fox Valley... Appleton/Oshkosh area. If you're ever up this way, let me know. I'd love to get a ride and I could do a nice photoshoot for you.
I'm looking at getting the latest JB4 with the 2-step cable and some downpipes... then I can run E85
Thoughts on JB4 vs. Cobb? I'm glad I have a K&N drop-in air filter... I was going to get the BMS DCI, but I've heard similar stories of a good drop-in filter being the best.

Definitely a possibility if there is ever a meet in that area this summer!
JB4 is more of a true tuner's solution. Cobb is more for Plug-n-Play when you just want a plain jane ezmode FBO setup to make great power. Until Cobb has Stage 3 maps out (or maybe they do and I've just been under a rock), then you're limited to the Stage 2+FMIC Aggressive which with great tires is good for 12 flat in the 1/4. Still very quick, but JB4 has meth control so if you want to step your game up and run e85 & meth with a custom tune for higher boost, that's where you start to see 11's.
Also Terry has a sterling reputation over at BMS and he is always available for support. You get more of a real service with JB4 because you're working with another enthusiast when you need support. Cobb is a big-box company supporting all kinds of different vehicles, and while there is a definite ease with installation and getting up and running, it does not come without tradeoffs.
So really it matters in regards to what you want to do. For me, I do a few track days a year, and I like having a 12 second car on the street. not many people can keep up if I want to pass, and on-ramps are absurdly fun. So Cobb is enough for me. That said, be careful with JB4 if you go meth/E85 - as soon as you go there, you will be pushing power numbers around 450, which is the limit for the stock clutch, as well as the standard differential.
You won't be putting that power down very well without also dropping a nice chunk of change to get a LSD. Basically, if you are enticed by higher boost, meth, and e85 then JB4 is for you, but be aware that above 400 whp is where you start to get into the very expensive part of modifying a 135i, and you will move closer to the "all-in" side of frankensteining a car

Currently my only mods are the jb4 and bms dci, and I run around 30% e85 with map 5 on the jb4. If I could just get rid of my fueling issues the car would be much more fun to drive...
For stock turbos a drop in filter will more than suffice, I went with the dci because I like to hear the spool and it looks nice when you pop the hood.
I consider the Cobb A/P a tuners tool, while the JB4 is more "out of the box tune" while running the generic maps. Map 5 is self learning, and there are some back end flashes which can be used via the combination of JB4 and A/P. I used an A/P on my last car (550 crank hp Subaru Legacy GT) and loved the device for switching between 91 octane and e85 maps. My tunes were pro tunes which were then stored on the A/P.
The downside of using the A/P, esp if you are under BMW warranty, is that it leaves a footprint in the DCM which says "I was flashed", whereas using the JB4 it's 100% stealth. The DCM only sees max stock boost (8 psi in my case) while the JB4 produces 16-17 psi.

Great info! I don't plan on running meth anytime soon, but do plan on mixing in a little E85 once I get the JB4. And for another $100, I can get the Walbro fuel pump and add up to 80% E85.
I don't plan on the clutch lasting forever, especially with 84k miles now. I'll swap in an ACT clutch once this one fails. It's currently holding real strong without any issue. I was unaware that the differential could have issues around 450whp. Either way, an LSD has been on my list once money permits. I'm on the hunt to break 11's with the 6MT... which is tough.

What fueling issues are you referring to? What kind of power are you seeing with those mods and 30% E85?
Also, how does one go about getting the "BMS backend flash" that I hear about on the forums? Do I have to purchase the COBB tuner then?
I'm long out of warranty, so that doesn't bother me

I still feel JB4 is more a tuner's tool given it has direct support for meth control, and it is produced by an active BMW tuner who has dedicated most of his focus to the N54/N55 platform. Terry is just an awesome resource. Cobb has so many maps nowadays, but yeah BMW warranty snoopers will get ya

I think you've got it right, then. And again I'm not saying the diff will blow up at 450, what I'm saying is you just won't put power to the ground well - you are honestly at a pretty high risk of losing control due to the very high amount of power that could be getting sent to 1 wheel instead of evenly distributed. At a certain power level, you just need an LSD in order to be safe.
