B58 Stock Vs Power Kit Vs Jb4
So I currently have 600 miles on my 340 and have enjoyed this engine very much so far. Just contemplating which way to go as far as tuning. The stock exhaust and cabin are very quiet compared to what I'm use too (m5 gthaus and A6 AWE) but I think I like it this way. I guess I'm getting old (32) The turbo spool noise it makes in 1st and 2nd gear is intoxicating. I currently have the power and sound kit on my lease but it's prorated so I don't pay the extra monthly till it's installed. I'm starting to think that I should just drop it all together and just go Jb4 and decide if I want an exhaust down the road. With tesla model 3 coming in a year and half I think more car enthusiasts will start getting accustomed to quieter cars that are fast. So I just wanted to ask you all what your plans are for your new 340i and 440i as far as tuning goes. Cheers

I'm taking delivery of my 340i xDrive this week. It has MPE, M sport, and track package, among others.
I am following the JB4 development closely and look forward to when it's out of beta so that I can install it. |

I've got the BMS intake coming Thursday. From there I'm waiting for the JB4 to come out of Beta, then I'll probably pull the trigger on it. My last mod would be a high flow cat from CG Precision. Those three mods would put me close to 400 hp&tq to the wheels which sounds awesome. Although it's in my nature to want to do it, I don't think I'll do any exhaust mods. I think just the high flow cat will be enough and still keep the car semi sleeper.
Btw, I studied the MPPK exhaust on real oem and discovered it weighs more than M performance exhaust (by a significant amount), and just by looks, probably weighs more than the stock exhaust too. Disappointing.

Just run a ton more boost. It's what everyone is doing and it's a lease so who cares. :

All I know is that I am not voiding the warranty on the first MY of an engine with the JB4.

I lease a 435i right now that has MPPK and MPE (which I currently have switched out for an Active Autowerke axle back) and I also have a JB4 and downpipe on it and I love the combination of both because the Power kit offers features like the exhaust burbles/fuel overrun sounds and improved throttle response too.
That being said, when I get a B58 car next, I'll probably opt to go with just JB4 and aftermarket exhaust since it seems to be the method that offers the most bang for my buck and I have had a pretty good experience with the jb4 on this car. The install/uninstall is relatively easy and the support from the guys at Burger is great. With the power that the JB4 can make, it's hard to resist, especially with how well the B58 seems to be doing with the beta tuner. |

Will be installing a JB4 on the shop's 340 once we order it
I have a posted thread about the JB4 gains with simple mods and a video showing the 340 beating a stock m4 With these kinds of gains and at the price offered for, it is a no brainer in my opinion Here is the thread i mentioned above http://f30.bimmerpost.com/forums/showthread.php?t=1213066
